- The common JFET current-source in Figure 1a has average output impedance and depends heavily on the JFET's V P and I DSS variations. These manufacturing variations limit the initial accuracy of the current setpoint that the circuit can obtain ...22-07-2021
- Many applications require the design of custom analog filters (Reference 1). The application for this design required simple and low-cost I/O filters for PLC (power-line communications), where low power consumption is a crucial factor. Figure 1 ...08-07-2021

- Many applications that use 110 V/230 V-ac mains require a ZCD (zero-crossing-detection) circuit for the ac-line voltage, for example, to synchronize the switching of loads. One method of ZCD uses a high-value current-limiting resistor or a ...01-07-2021

- The simple ADC in Figure 1 is perfect for getting analog signals into a purely digital microcontroller. Using just five surface-mount parts, you can assemble it for less than 50 cents (1000), which is approximately half the cost of a ...10-06-2021
- Deadband circuits find applications in servo-control systems. A precision current source and a half-wave inverting rectifier form a positive deadband circuit (Figure 1). The REF01 , IC 1 , is a precision 10 V voltage reference. It forms a precision ...01-06-2021
- A typical window comparator uses two comparators and a single op amp to determine whether a voltage is inside or outside a boundary region. Figure 1 shows a typical implementation. IC 1 is an inverting op amp with a gain of 1. V REF and V REF ...31-05-2021
- Frequency multipliers typically work with square waves. However, the circuit in Figure 1 performs frequency multiplication on triangle waveforms and maintains the input's amplitude and uniformity. Figure 1. This circuit performs frequency ...18-05-2021
- Accurate op amps have high open-loop gain, low offset voltage and current, low voltage and current noise, and low distortion. However, they often lack the ability to provide high output currents while maintaining all the other high-accuracy ...18-04-2021
- Light sensors find use in a host of important applications, spanning from consumer electronics, such as ambient-light measurements and exposure control for cameras, to scientific instruments, such as optical-absorption spectroscopy, IR (infrared) ...14-04-2021
