Collector follower amplifier
WebCommon collector amplifier has collector common to both input and output. It is called the common-collector configuration because (ignoring the power supply battery) both the signal source and the load share the collector lead as a common connection point as in Figure below. Common collector: Input is applied to base and collector. WebMar 16, 2024 · A common collector amplifier is constructed using an NPN bipolar transistor and a voltage divider biasing network. If R 1 = 5k6Ω, R 2 = 6k8Ω and the supply voltage is 12 volts. Calculate the values of: V B, V …
