- A Resistance Capacitance (RC) Coupled Amplifier is basically a multi-stage amplifier circuit extensively used in electronic circuits.
- In this amplifier, two common emitter amplifiers are connected through a coupling capacitor (CC).
- The output from the emitter of the first amplifier is the input to the base of the second amplifier.
- The purpose of the coupling capacitor is to block DC voltage and pass AC voltage.
- As a result of this, there is no DC interaction between stages i.e. the DC voltage of the first stage does not disturb the operating point of the second stage.
- Polyester film capacitors is commonly used for coupling between two circuits.
