The requirements for a good current source is the one in which, (Take Output current – IO and Output resistance – rO )
A. IO independent upon current gain and should be low
B. rO should be very high
C. IO in the circuit should be low
D. IO independent upon current gain and rO should be very high
Answer:A
The requirements for a good current source is the one in which, (Take Output current – IO and Output resistance – rO )
A. IO independent upon current gain and should be low B. rO should be very high C. IO in the circuit should be low D. IO independent upon current gain and rO should be very high
Explanation: The need for high output resistance current source can be seen because the common mode gain of the differential amplifier can only be reduced by using high resistance current sources.
