KIITEE Mock Test - 4 - Question 1

Save

In a common-base amplifier, the phase difference between the input signal voltage and output voltage is

A.
0
B.
π/4
C.
π/2
D.
π

Detailed Solution for KIITEE Mock Test - 4 - Question 1

A common-emitter amplifier is shown in the figure (A).
In this Circuit , the output signal is an amplified version of the input signal and is 180 degrees out of phase with the input signal.

Common emitter Amplifier

Common Base Amplifier

Figure (B) is a common-base amplifier. In this circuit the output signal is an amplified version of the input signal and is in phase with the input signal. In both of these circuits, the output signal is controlled by the base-to-emitter bias. As this bias changes (because of the input signal) the current through the transistor changes.

KIITEE Mock Test - 4 - Question 2

Save
