Class C Amplifier Circuit Diagram. Using the class c amplifier the pulses produced at its output can be converted to complete sine wave of a particular frequency by using lc circuits in its. Again notice input input a input voltage cutoff level i i eout 11 ii i output ii 11 current b or vcc vcc b figure 3.
Here in this condition vout vin vbe1. In the above circuit the biasing resistor rb is used to pull the base terminal of the q1 transistor further downwards. Class c power amplifier circuit diagram.
There is a trade off between efficiency and distortion as the efficiency improves at a large extended level by reduced conduction angle.
Maximum 80 efficiency can be achieved in radio frequency related operations class c amplifier uses less than 180 degree conduction angle. The schematic diagram for push pull amplifier circuit consists of two transistor q1 and q2 which are npn and pnp respectively. Maximum 80 efficiency can be achieved in radio frequency related operations class c amplifier uses less than 180 degree conduction angle. The importance of an amplifiers input and output impedance is discussed in ac theory module 7 and using nfb to control impedance is described in amplifiers module 32.
