Answer:A
Which circuit is used as active load for an amplifier
A. Wildar Current source B. Darlington pair C. Current Mirror D. All of the mentioned
Explanation: Current mirror has DC resistance (order of few kΩ), as quiescent voltage across it is a fraction of supply voltage and current in milliampere. 7. What is the equation of load current for a differential amplifier with an active load?
