Why active load is used in amplifier to obtain large gain in intermediate stage of amplifier?
A. To obtain a very large voltage gain
B. To get High input resistance
C. To reduce the noises
D. To increase current gain
Answer:A
Why active load is used in amplifier to obtain large gain in intermediate stage of amplifier?
A. To obtain a very large voltage gain B. To get High input resistance C. To reduce the noises D. To increase current gain
Explanation: To increase gain usually large collector resistance value as gain is proportional to load resistor. However, due to limitation of maximum value load resistor, active loads are used in amplifier to obtain large gain in intermediate stages of amplifier.
