Which is preferred to attain higher input resistance and the output amplitude equal to input?
A. Voltage follower
B. Voltage series feedback amplifier
C. Voltage shunt feedback amplifier
D. Inverter
Answer:A
Which is preferred to attain higher input resistance and the output amplitude equal to input?
A. Voltage follower B. Voltage series feedback amplifier C. Voltage shunt feedback amplifier D. Inverter
Explanation: In the voltage follower the output follow the input due to unity gain. Therefore, it is attained to get higher input resistance and output amplitude equal to input.
