RC coupled amplifier
- A Resistance Capacitance (RC) Coupled Amplifier is basically a multi-stage amplifier in which two CE amplifier are connected through a coupling capacitor.
- This coupling capacitor blocks the DC voltage and passes the AC voltage from the input to the output.
- In this kind of amplifier, the input signal applied at the base of the transistor in stage 1 (Q1) is amplified and appears at its collector terminal with a phase-shift of 180°.
- This is further amplified and is passed-on as an output of the second stage and is available at the collector terminal of Q2 after being shift by 180° in its phase.
- This means that the output of the second stage will be 360° out-of-phase with respect to the input, which indicates that the phase of the input signal and the phase of the output signal obtained at stage II will be identical.
