Diac: Operation, Applications, Testing

A diac is a three-layer, two-terminal bidirectional device that is typically used as a triggering device to control the gate current of a triac. See Figure 1. A diac is a special diode that can be triggered into conduction in either direction. Figure 1 A diac is a three-layer, two-terminal …

Operational Amplifier (Op Amp): Basics, Operation, Applications

operational amplifier

An operational amplifier (op-amp) is one of the most widely used integrated circuits (ICs). An operational amplifier (op-amp) is a high-gain, directly coupled amplifier that uses external feedback to control response characteristics. See Figure 1. Figure 1. Types of operational amplifiers (op amps) include dual-power and high-current, high-power op amps. …

DC Power Supply Filter Types

A filter is a circuit in a power supply section that smooths the pulsating DC to make it more consistent. A filter minimizes or removes ripple voltage from a rectified output by opposing changes in voltage and current. The filtering process is accomplished by connecting parallel capacitors and series resistors …
