Common collector biasing

WebA common-collector circuit can be used as an AC-coupled linear amplifier by biasing its base to a quiescent half-supply voltage value (to accommodate maximal signal swings) and AC-coupling the input signal to its base and taking the output signal from its emitter, as shown in the basic circuits in Figures 14 and 15. WebJun 12, 2024 · R L, which is essentially a collector resistor, is needed to establish collector current I C and voltage at collector V C. As for common base configuration, a bypass capacitor is placed across R 2 so that at signal frequencies, it’s equivalent to a low reactance path to ground. This would essentially ground the base terminal for ac signals ...
