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.
Objectives. After studying this chapter, you should be able to: Show how the dc load line, ac load. line, and Q point are determined for CE and CC power amplifiers. Calculate the maximum peak-to-peak (MPP) unclipped ac voltage.
The class A power amplifier as discussed in the previous chapter, is the circuit in which the output current flows for the entire cycle of the AC input supply. We also have learnt about the disadvantages it has such as low output power and efficiency.
Utilize these free study guide on power amplifiers and learn basic electronics. Covers the basics and some advanced concepts around power amplifiers.
9 Ιαν 2014 · Class C power amplifier is a type of amplifier where the active element (transistor) conduct for less than one half cycle of the input signal. Less than one half cycle means the conduction angle is less than 180° and its typical value is 80° to 120°.
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.
