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

(A) $\frac{π}{4}$
(B) $π$
(C)0✓ Correct
(D) $\frac{π}{2}$

Answer: (C)

Solution

In the common-base arrangement the input is applied at the emitter and the output taken at the collector, and these move in step with each other. The common-base amplifier produces no phase reversal, so the phase difference between input and output voltages is
