Gate Controlled Switch (GCS) Circuit - Operation and Advantages: As mentioned earlier, low-current drop out is the normal way in which the SCR is turned off. Gate controlled switch is…
Modulation - Definition, Types and Need for Modulation: Any wave has three significant characteristics viz. amplitude, frequency and phase, and modulation is a process of impressing information to be transmitted…
Large Signal Tuned Amplifier - Operation and its Equivalent Circuit: Tuned amplifier circuits are for class A operation and their use is limited to applications in which RF signal has…
Class D Power Amplifiers - Circuit Diagram, Operation and Applications: Historically, audio amplifiers have been configured as class A, class B or class AB and the art of design is…
Class B Power Amplifier - Operation and Efficiency derivation: In Class B Power Amplifier operation, the transistor is so biased that zero signal collector current is zero. Hence class B…
Classification of Power Amplifiers: Classification of Power Amplifiers are primarily divided into two categories viz. audio power amplifiers and radio power amplifiers. Audio power amplifiers, also called the small signal…
Step Response of an Amplifier: An alternative criterion of amplifier fidelity is the response of the amplifier to a particular input waveform. Of all possible available waveforms, the most generally…
Operation of Oscillator Circuit: The use of positive feedback that results in a feedback amplifier having closed-loop gain |Af| exceeding unity and satisfies the phase conditions results in operation as…
