Question

Quizplus · Accepted Answer

The common-collector circuit, also known as the emitter follower circuit, provides a high input impedance and a low output impedance. This configuration allows the output voltage to follow the input voltage with a small voltage drop at the output. This makes it an ideal configuration for providing high current gain, which is essential for increasing the current-handling capability of a zener diode. Therefore, the zener follower is typically implemented using a common-collector circuit.
