Class C Power Amplifier. When the collector current flows for less than half cycle of the input signal, the power amplifier is known as class C power amplifier. The efficiency of class C amplifier is high while linearity is poor. The conduction angle for class C is less than 180 o.
The function of a power amplifier is to raise the power level of input signal. It is required to deliver a large amount of power and has to handle large current.
A Class A power amplifier is one in which the output current flows for the entire cycle of the AC input supply. Hence the complete signal present at the input is amplified at the output. The following figure shows the circuit diagram for Class A Power amplifier.

Class C Power Amplifiers – Circuit Diagram, Operation and Applications: A class C power amplifiers is biased to operate for less than 180° of the input signal cycle, as shown in Fig. 17.22. The tuned circuit in the output, however, will provide a full cycle of output signal for the fundamental or resonant frequency of the tuned circuit (L ...
POWER AMPLIFIER. 2.0 Introduction. The main characteristics of an amplifier are Linearity, efficiency, output power, and signal gain. In general, there is a trade off between these characteristics. For example, improving amplifier’s linearity will degrade its efficiency.
31 Ιουλ 2024 · Power amplifiers with a conduction angle lower than 180 degrees are known as Class C amplifiers. In this article, we’ll examine the operation of Class C amplifiers and explore the impact of a lower conduction angle reduction on various power amplifier performance parameters.
