Audio Amplifier Circuit Design Tutorials

Amplifiers are the backbone of Analog electronics. They are used vastly in the field of electronics industry. Amplifiers are used almost in all the audio related applications.  Power amplifier are designed to maximize the magnitude of the power of given input signal. In audio electronics, the operational amplifier increases the voltage of the signal, but unable to provide the current, which is required to drive a load.
