Class A Power Amplifiers (Direct Coupled with Resistive Load): A class A power amplifiers is defined as a power amplifier in which output current flows for the entire cycle (360°)…
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…
Transformer Coupled Transistor Amplifier - Working Principle: The main cause for low voltage and power gains of an R-C coupled amplifier is that the effective load (Rac) of each stage…
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…
What is Multistage Amplifier? - Types, Block Diagram and Analysis Amplifiers that produce voltage, current, and/or power gain through the use of two or more stages are called multistage amplifiers.…
Applications of FETs (Field Effect Transistors): Applications of FETs - FET has a very high input impedance (100 MΩ in case of JFETs and 104 to 109 MΩ in case of…
Selection of Oscillator: While in the Selection of Oscillator for a particular application, the following particulars are to be considered. Frequency Range: The oscillator selected for a particular application should…
Crystal Oscillators - Circuit, Working, Advantages and Disadvantages: In crystal oscillators, the usual electrical resonant circuit is replaced by a mechanically vibrating crystal. The crystal (usually quartz) has a high…
