Compensating Network in Op Amp: In op-amps the variations in gain and phase shift with respect to frequency are due to the internal capacitors and stray capacitances, which are due…
CMRR of Op Amp Formula (Common Mode Rejection Ratio): One of the more common features of a differential amplifier is its ability to cancel out or reject certain types of…
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…
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)…
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…
Power BJT - Construction, Operation and its Characteristics: Power transistors are large-area devices. Because of differences in geometry and doping concentrations, their properties tend to vary from those of the…
Radio Communication System - Block Diagram and types: Radio communication is very popular technique of communicating a message. The radio waves are electromagnetic waves produced due to escape of electrical…
Emitter Follower Circuit - Operation, Advantages and Applications: Emitter Follower Circuit is also a negative current feedback circuit. This circuits exhibits a large input impedance, a small output impedance, and…
