Question

if a 10 mv signal is applied to the base of the emitter - follower circuit, the output signal is approximately
select one:
○ a. 10 mv
○ b. 150 mv
○ c. 100 mv
○ d. 1.5 v

Explanation:

An emitter - follower (common - collector) circuit has a voltage gain close to 1. This means that the output voltage is approximately equal to the input voltage (with a very small voltage drop across the base - emitter junction, but for approximation, we can consider the output voltage to be nearly the same as the input voltage). Given an input of 10 mV, the output should be approximately 10 mV.

Answer:

a. 10 mV
