A widlar current source is used
A. to get low value of current
B. to get high value of CMRR
C. to get low voltage of gain
D. to get high value of Output
Answer:A
A widlar current source is used
A. to get low value of current B. to get high value of CMRR C. to get low voltage of gain D. to get high value of Output
Explanation: In the widlar current source Re is added to emitter lead of transistor, which consequently results in smaller output current value.
