The THD is usually expressed in percentage. Like if an amplifier has 2 percent THD, it means that the power of all the harmonics combined is just 2 percent of the power of the original frequency. Generally, THD up to 10 percent is tolerable but it should be as low as possible. Standard Audio amplifiers have a THD as less as 1 percent or 0.5 percent.

Amplifiers are used to increase the amplitude of a voltage or current, or to increase the amount of power available usually from an AC signal. Whatever the task, there are three categories of amplifier that relate to the properties of their output; 1. Voltage amplifiers. 2. Current amplifiers. 3. Power amplifiers.

• A Class A amplifier is defined as one in which the output device is conducting for the complete waveform cycle. Anything less than complete conduction of all output devices is not class A • As with any audio amplifier, the signal should be biased in the middle of the linear region. • Class A amplifiers are the least efficient of all amplifiers

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.
