When a transistor amplifier having current gain of `75` is given an input signal, `V_(I) = 2 sin (157 t + pi//2)`, the output signal is found to be `V_(o) = 200 sin(157 t + 3pi//2)`. The transistor is connected as :

A

a common base amplifier

B

a common collector amplifier

C

an oscillator

D

a common emitter amplifier

Text Solution

Verified by Experts

The correct Answer is:
D
There is a phase difference of `pi` between `V_i` and `V_o` in a CE amplifier.
