Class D power amplifier. Class D power amplifier is a type of audio amplifier were the power handling devices are operated as binary switches. Since the power handling…
Class C power amplifier. Class C power amplifier is a type of amplifier where the active element (transistor) conduct for less than one half cycle of the input…
In class AB power amplifiers, the biasing circuit is so adjusted that the operating point Q lies near the cut-off voltage. During a small portion of negative…
Harmonic distortion in power amplifiers. Distortion is a serious problem faced in power amplifier design. In faithful amplification the output signal must be a scaled replica of the…
Class B power amplifier. Class B amplifier is a type of power amplifier where the active device (transistor) conducts only for one half cycle of the input signal.…
Class A power amplifier. Class A power amplifier is a type of power amplifier where the output transistor is ON full time and the output current flows for…
Practical power amplifier. Audio power amplifier is an amplifier which produces amplification of power between the input and output. Theoretically every audio amplifier produces some amount of power…
Introduction To Power Amplifiers An amplifier system consists of signal pick-up transducer, followed by a small signal amplifier(s), a large signal amplifier and an output transducer. A transducer…
