High output resistance and small input resistance can truly transmit input signal to the load, then the signal source currentis low. Voltage follower is a common collector circuit, and the signal is input from the base and output from the emitter, so it is also known as emitter device. Base voltage and collector voltage have the same phase, that is, the input voltage and output voltage is in-phase. The main features of this circuit are: high input resistance, low output resistance, voltage gain is approximately 1, so it is called a voltage follower.
