Change in value of common mode input signal in differential pair amplifier make
A. Change in voltage across collector
B. Slight change in collector voltage
C. Collector voltage decreases to zero
D. None of the mentioned
Answer:A
Change in value of common mode input signal in differential pair amplifier make
A. Change in voltage across collector B. Slight change in collector voltage C. Collector voltage decreases to zero D. None of the mentioned
Explanation: In differential amplifier due to symmetry, both transistors are biased and matched. Therefore, Voltage at each collector will be same.
