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…
Transformer Coupled Class A Power Amplifier: Transformer Coupled Class A Power Amplifier also sometimes referred to as single ended power amplifier. The term "single ended" (denoting only one transistor) is…
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…
Difference between Voltage Amplifier and Power Amplifier: The Difference between Voltage Amplifier and Power Amplifier are discussed below The primary function of the voltage amplifier is to raise the voltage…
n Stage Cascaded Amplifier: As already discussed, several amplifier stages are usually cascaded to increase the overall voltage gain of the amplifier. However, sometimes cascading is done to obtain the…
Classification of Amplifiers: In the Classification of Amplifiers, the transistor amplifiers may be classified in several ways such as on the basis of transistor configuration used, active device used, output,…
Various Bias Compensation Methods: During the discussion made for various biasing methods for providing stability to the operating point we have seen that self bias (or potential divider bias) and…
Self Bias or Potential Divider Bias Circuit: This is the most commonly used biasing arrangement. The arrangement of Self Bias or Potential Divider Bias Circuit is shown in Fig. 12.17…
