Bistable Multivibrator - Working and Types: A bistable multivibrator, as its name implies, has two stable states. It can stay in either of the two states indefinitely (as long as dc power supply remains on).…
Monostable Multivibrator - Operation, Types and Application: Monostable multivibrator is a two-stage amplifier with two states—one stable state and another quasi-stable state. The circuit has two transistors Q1 and Q2, one being in the offstate,…
Astable Multivibrator Definition and its Working: The multivibrator circuit which has no stable state is called the astable multivibrator. The two states of operation of astable multivibrators are quasi-stable (temporary) states. The astable multivibrator, therefore,…
Multivibrator definition and Types (Astable, Monostable and Bistable): A multivibrator is basically a two stage R-C coupled amplifier with positive feedback from the output of one amplifier to the input of the other, as illustrated…
Switching Characteristics of Power MOSFET: Power MOSFET is an enhancement mode device modified to handle much large currents and voltages than a conventional MOSFET. Prior to the invention of the power MOSFETs, MOSFETs could not…
Transistor as a Switch Circuit Diagram and Working: The Transistor as a Switch Circuit Diagram and Working can be explained with the help of its output characteristics. Figure 31.2 shows the output characteristics of a…
What is Switching Circuit? In practice, we often need making (switching on) and breaking (switching off) of an electrical circuit. It is also desirable and sometimes essential that the switching operation (making and breaking of…
Double Differentiation - Derivation: Two R-C coupling networks in cascade separated by an amplifier A is shown in Fig. 29.36 (a). The amplifier A is to operate as a linear amplifier and the output impedance…
RC Integrator Circuit Diagram and its Application: A circuit that gives an output voltage directly proportional to the integral of its input is known as integrating circuit. Figure 29.18 shows a typical RC Integrator Circuit…
Low Pass RC Circuit Diagram, Derivation and Application: The Low Pass RC Circuit is shown in Fig. 29.18. In a Low Pass RC Circuit, the output voltage vout is taken across the capacitor. Resistance offers…
