What are matching resistors?What are the functions of matching resistors?

　　In the design and manufacturing process of electronic products, PCB (Printed Circuit Board) board design is a crucial link. In PCB board design, the use of matching resistors plays a decisive role.　　So, what exactly is a matching resistor? What role does it play in PCB board design? This article will provide an in-depth analysis of the importance and specific role of matching resistors in PCB board design.　　What are matching resistors?Matching resistors refer to resistors that have nearly identical electrical characteristics, including resistance values, tolerance, and temperature coefficients. These resistors are specifically chosen and paired to ensure that the electrical properties across different parts of a circuit are as uniform as possible. This matching process is critical in applications where balance, precision, and stability are essential.　　What are the functions of matching resistors?　　1. Impedance matching　　Impedance matching is the most direct and important role of matching resistors. In circuits with high-speed signal transmission, the integrity of the signal largely depends on whether the impedance of the circuit is matched.　　If the impedances of the transmitter and receiver do not match, the signal will be reflected during transmission, resulting in signal distortion or even complete loss.　　By reasonably setting matching resistors in the circuit, the impedances of the transmitting end and the receiving end can be matched, thereby reducing signal reflection and distortion and ensuring signal integrity and stability.　　2. Terminal matching　　In addition to impedance matching, matching resistors are also commonly used for termination matching. In long-line transmission or high-speed digital signal transmission, due to the inductance and capacitance effects of the line, the signal may ring at the end of the transmission line.　　By connecting a matching resistor in parallel to the ground at the end of the transmission line or connecting a matching resistor to VCC (positive power supply), the reflected signal can be effectively absorbed, the ringing phenomenon eliminated, and the signal transmission quality improved.　　3. Voltage division and current limiting　　In addition to the above two main matching functions, matching resistors can also play the role of voltage dividing and current limiting in the circuit.　　In some situations where precise control of voltage or current is required, precise adjustment and control of voltage or current can be achieved by reasonably setting the resistance of the matching resistor.　　In addition, in some situations where sensitive devices need to be protected from excessive current impacts, matching resistors can also be used as current-limiting resistors to protect the circuit.　　What’s the application of matching resistors?　　● Amplifier Circuits:　　In amplifier circuits, matching resistors are often used in critical stages to maintain balance and symmetry. Balanced resistors help ensure that signals passing through the amplifier are accurately amplified without distortion. This is particularly important in audio applications where fidelity is a key consideration.　　● Voltage Divider Networks:　　In voltage divider circuits, matching resistors are employed to divide an input voltage into precise fractions. Any mismatch in resistor values can result in inaccurate voltage division, leading to errors in the output signal. Precision is crucial in applications like sensor networks and measurement devices.　　● Bridge Circuits:　　Wheatstone bridge circuits, commonly used in precision measurement applications, rely on the accurate matching of resistors. This ensures that the bridge is balanced, providing accurate and stable readings in applications such as strain gauge sensors and temperature sensors.　　● Feedback Networks:　　Matching resistors play a crucial role in feedback networks of operational amplifiers. In circuits employing negative feedback, the resistors are often matched to maintain a stable and predictable gain, contributing to the overall performance and reliability of the amplifier.　　Principles for selecting matching resistorsWhen selecting matching resistors, certain principles need to be followed to ensure circuit performance and stability.　　First, the resistance of the matching resistor must be determined based on the operating frequency of the circuit and the characteristic impedance of the transmission line. Secondly, the power handling capacity of the matching resistor should be considered to ensure that it will not be damaged due to overheating during operation.　　In addition, factors such as the accuracy and stability of the matching resistors need to be considered to ensure that their impact on circuit performance is minimized.

What is capacitor polarity? How do you determine the polarity of a capacitor?

　　Capacitor is an electronic element which is passive in nature. This electronic element is utilized for storing charge. The capacitors are of two types: Polarized and non-polarized. Capacitor polarity is defined as having either negative or positive charge on the capacitor. The capacitors with no signs or charge are known as non-polarized capacitors. This element consists of two leads or ends. One off the end is positive or anode and the other is cathode or negative.　　What is capacitor polarity?　　Capacitor polarity can be elaborated as having a negative or positive influence or charge on the terminals of the capacitor. Numerous methods are advised for finding the capacitor polarity. The capacitors polarity can be distinguished by looking at its terminal’s length. The one with longer lead is supposed to be anode or negative terminal of the capacitor while the one with shorter lead is positive and one with large length is negative. Non-polar capacitors have nothing relevant to the specific format when it is to be connected within a circuit.　　Is capacitor always negative?　　No, the capacitor is not always negative; however, when connecting the capacitor with a source of voltage, the charge or potential of the capacitor can be determined. Capacitor polarity is needed to be considered because if ignored then its layer of oxide becomes vulnerable to damage and avalanche current is drawn by capacitor making it out of work or even destroyed.　　Are capacitors polarity sensitive?　　A total of three layers are present in capacitor when its fabrication process is considered. The layer which is for insulation is known as dielectric. It is in the middle of the anode and cathode which are metallic sheets. The anode and cathode are always in parallel to each other. The insulator is supposed to be in the middle of the sheets of metal. The main purpose of dielectric is that it separates the electrodes.　　The polarized capacitors are always polarity sensitive. The basic rules of the circuit theory must be obeyed in order to allow capacitors to work. For installation of a polar capacitor within a circuit, its polarity is surely to be considered. Capacitor polarity if ignored can cause damage to the circuit and to the capacitor as well.　　How do you determine the polarity of a capacitor?　　There are a number of ways through which the capacitor polarity can be determined. During the process of fabrication of capacitor, its polarity is to be taken care off. Some kinds of capacitors are having bars for its positive and negative terminals identification.　　The one with longer lead is supposed to be anode or positive terminal of the capacitor while the one with shorter lead is a cathode or negative terminal. However, sometimes the terminals have equal length and it gets very difficult to identify the terminal. Working out on the polarity of capacitor is of great importance as it will destroy the capacitor or even entire circuit if connected in wrong manner when the capacitor is polar in nature.　　Which capacitor must be connected with the correct polarity?　　The polar capacitors must be connected in a proper way within the circuit in accordance to the polarity of the circuit. The polarized capacitors never gets damaged with the heat when soldering is in progress.　　What are the examples of capacitor polarity?　　The following are some major and famous types of capacitor polarity.　　Electrolytic capacitors　　Electrolytic capacitors are widely utilized kind of capacitors. Such are of polar kind and are manufactured in two styles i.e., axial and radial. Both terminals of radial capacitors are on same side. Both sides of axial capacitors are on opposite sides. The radial capacitors are cheaper in price and also small in size.　　Tantalum capacitors　　Capacitor polarity is mentioned on tantalum capacitors too. These capacitors are having lower voltage and current ratings. These are of small size. Such capacitors are very expensive. Tantalum capacitors are only used for high demand and sensitive applications.　　Ceramic capacitors　　These are often in round shape and its ratings and values are mentioned on it. The length of its leads or terminals is answer to its positive and negative terminal like electrolytic capacitors. The applications of ceramic capacitors comprise of RF devices.　　Super capacitors　　Ultra-capacitor is another name given to super capacitor and such capacitors may range up to certain thousand Farads. Such elements are used in applications like consumer electronics.　　Film capacitors　　Such capacitors are in square or rectangular shape. Film capacitors are cheap and economical. These elements are having less frequency response. These are small in size and are utilized in most of the electronic equipment.　　How do you check capacitor polarity with a multi-meter?　　For determining the capacitor polarity with the help of a multi-meter, the device is to be set at higher resistance measuring range up to 1 Mega Ohms. The multi-meter is then to be connected to the legs of capacitor for its terminal identification. The red lead of multi-meter is to be connected to positive terminal while black lead is to be attached to negative terminal. Monitoring the meter to start reading from zero and slowly moving to measure higher resistance until infinity is reached.　　What happens if you reverse the polarity of a capacitor?　　In case if the polarity of the capacitor is reversed then the capacitor may get damaged because of the flow of high amount of current through it. Another possibility is that it may create a short-circuit destroying entire circuit.

ROHM's New Zero-Drift Op Amp with High Accuracy Regardless of Temperature Changes

　　ROHM has developed a zero-drift operational amplifier (op amp) - the LMR1002F-LB. It is designed for industrial and consumer electronics devices and minimizes both input offset voltage and input offset voltage temperature drift. Capable of accurately amplifying output signals from sensors installed in various measurement devices, this new op amp is ideal for current sensing applications such as power control inverters and temperature/pressures/flow/gas detectors.　　As automotive and industrial equipment become more sophisticated and application control requirements are more precise, environmental sensors are increasingly being used to quantify temperature, pressure, and gas concentrations such as carbon dioxide to foster a sustainable society. However, sensor signals are so small that amplification is necessary, and if a general op amp with 1mV offset voltage is used to amplify the sensor signal by a factor of 1,000, for example, the offset voltage also increases by this amount - resulting in a voltage error of 1V (1,000mV) in the signal output. At the same time, input offset voltage temperature drift, which varies according to temperature and time, is difficult to compensate for.　　In response, ROHM developed a zero-drift op amp that addresses these problems by leveraging proprietary analog circuit technology - cultivated over many years. The LMR1002F-LB is ROHM’s first zero-drift op amp using the chopper method. In contrast to conventional low-offset op amps featuring a typical input offset voltage of 150µV (Max.), ROHM’s new product limits input offset voltage to just 9µV (94% lower). This eliminates the need for peripheral components or software to adjust the input offset voltage, reducing both design person-hours and costs. On top, input offset voltage temperature drift is just 0.05µV/°C (Max.) in the operating temperature range of -40°C to +125°C - the lowest among ROHM’s op amps. Enabling accurate amplification of measured sensor signals without being affected by environmental changes such as temperature contributes to high accuracy control of industrial equipment in factories. This, coupled with a wide supply voltage range of 2.7V to 5.5V and rail-to-rail input/output, make it ideal for a variety of industrial applications.　　Going forward, ROHM will continue to improve the performance and expand its lineup of zero-drift op amps. Moreover, ROHM will work to improve the performance of op amp lineups by reducing noise and offset - while increasing power savings, and expand the power supply voltage range demanded in the automotive and industrial equipment markets. The overall goal: contributing to solving social issues through higher accuracy application control.      Product Lineup　　Application Examples　　• Industrial equipment: Power control inverters, photovoltaic inverters, storage battery monitoring, pressure gauges, flow meters, temperature controllers, gas detectors, etc.　　• Consumer appliances: Refrigerators, washing machines, air conditioners, etc.　　Online Sales Information　　Sales Launch Date: December 2023　　Pricing: $8.0/unit (samples, excluding tax)　　The product will be offered at other online distributors as it becomes available.　　■Product Information　　Applicable Part No: LMR1002F-LB　　Terminology　　Input Offset Voltage　　Refers to the error voltage that occurs between the input terminals of an op amp.　　Input Offset Voltage Temperature Drift　　The fluctuation in input offset voltage caused by a rise/fall in temperature. The smaller this value is the higher the op amp accuracy. Zero-drift op amps automatically compensate for input offset temperature drift.　　Chopper Circuit　　A circuit configured to detect the offset voltage generated inside an op amp and automatically correct it via digital circuit control. This cancels offset voltage by feeding back the offset voltage stored as capacitance in the circuit using a voltage-current conversion circuit.　　Rail-to-Rail Input/Output　　A circuit format that allows the input and output voltages of an op amp to accommodate the entire supply voltage range. The supply voltage in this case is called a Rail.

What are direct current and alternating current?

　　What is direct current?　　Direct current refers to a current whose magnitude and direction do not change within a certain time range. Many electrical appliances that do not contain inductive components are driven by direct current, such as radios, speakers, etc.　　What is alternating current?　　Alternating current refers to a current that continuously changes periodically in magnitude and direction. Usually alternating current changes according to the sine law or the cosine law. The current first changes from zero to the maximum, then from the maximum to zero, and then from zero in the opposite direction. It changes to the maximum, then changes from the maximum to zero, completing a cycle, and changes like this repeatedly.　　Direct current VS alternating current – what are the differences?　　Flow of Current:　　Direct Current (DC): The current flows continuously in one direction. Electrons move in a single direction, like in a battery-powered circuit.　　Alternating Current (AC): The current changes direction periodically at a certain frequency. Electrons oscillate back and forth in direction over time. Household electricity and power grids commonly use AC.　　Generation:　　Direct Current (DC): Typically generated by devices like batteries, solar panels, or DC generators.　　Alternating Current (AC): Produced in power plants using generators and transformers to create alternating currents.　　Applications:　　Direct Current (DC): Used in battery-powered devices such as phones, computers, electric vehicles, and equipment requiring stable voltage.　　Alternating Current (AC): Widely used in household electricity, industrial equipment, and power transmission systems due to its ability to easily adjust voltage using transformers, transmit power over long distances, and convert to different voltage levels conveniently.　　The role of direct currentDirect current is widely used in various situations. The following are its main uses:　　Test equipment for research units and laboratories and power supply for product aging life experiments.　　Charging batteries.　　Automotive applications.　　Manufacturing testing.　　Other low voltage, low current applications.　　The function of alternating currentAlternating current is widely used in daily life and industry. Its main functions include:　　Transmitting power over long distances: AC is more suitable for long-distance power transmission because its voltage and current are stable and there is less loss during transmission.　　Powering household appliances: Almost all household appliances such as televisions, air conditioners, refrigerators, ovens, etc. use AC as the power source.　　Driving electric motors: AC is widely used to drive various electric motors such as household washing machines, automobiles, fans, pumps, and high-speed trains.　　Lighting: Modern lighting systems, such as LED lights and fluorescent lights, also use AC as a power source.　　Provides stable power supply: The stability of AC power makes it ideal for industrial and commercial purposes, especially where precise control of power supply is required.　　Flexibility: AC power can be controlled through a transformer or frequency converter, making household appliances and other equipment work more stably.　　Applicability: In some specific scenarios, such as high altitude areas or ships, DC power cannot be used, and AC power becomes the only option.　　Conclusion　　In general, alternating current has great advantages in power supply, transmission and portability. These advantages make alternating current an indispensable form of energy in daily life and industrial production.
