Classification of power amplifiers: class A, B, C amplifiers, Lectures – XXVI, XXVII.
Electronic systems need voltage amplification followed by power amplification. It is the voltage of output after signal is amplified to higher voltage level which drives the power amplifier. Transistor of high β (corresponds to thin base) is used for voltage amplifiers. But small β (which corresponds to thick base) are used in power amplifiers. According…
