In all audio amplifiers, the feedback exists in two distinct forms. DC feedback is applied to keep the DC offset of the amplifier output very small (generally less than +/-50mV). AC feedback sets the overall voltage gain of the amplifier, and minimizes distortion.

An Amplifier increases the strength of an audio signal by increasing its amplitude. The rise in amplitude is called Amplification. That is why, it is called Amplifier. An audio amplifier needs to be designed based on its application and required specifications.

In simple words an audio amplifier may be explained as a device which is able to increase or “magnify” input audio electrical signals to a magnitude which may be relatively much higher than the applied input. This conversion of a low power input signal into a high power output signal is termed as amplification and is measured in watts.

At the heart of every amplifier is a device that uses one signal to control another. In electronics, this means a device that uses a small voltage or current signal to control a larger voltage or current. The first electronic amplifying circuits were constructed with devices called electron tubes instead of transistors. Tubes still find specialized applications in electronics, but they …

CD stage amplifier is suitable for output stage of OPAmp due to its low output impedance and large bandwidth. However, in CMOS analog IC, CS stage is more widely used for output stage OPAmp than CD stage. Why? 2/22/2011 Insoo Kim.

The voltage amplifiers described in Amplifiers Modules 1 to 4 can increase the amplitude of a signal many times but may not, on their own, be able to drive an output device such as a loudspeaker or motor. For example a voltage amplifier may have a gain of 100 and be able to amplify a 150mV signal to
