Keywords: Ripple Voltage, AC power supplies, audio amplifier, open-loop

Capacitors are used to couple each stage of an amplifier to the next, to help remove ripple voltages from rectified AC power supplies and they are also used to tune circuits to get the required frequency response, such as a tone control in an audio amplifier, or an RF or IF amplifier in a radio receiver front-end.

Capacitors are also used to bypass emitter resistors to improve the voltage swing and lower the AC output impedance of class A amplifier stages, and also used in negative feedback loops to stabilize an amplifier's open-loop gain.
