Response to the following question:
AMOS differential amplifier biased with a current source I =200 μA is found to switch currents completely to one side of the pair when a difference signal vid =0.3 V is applied. At what overdrive voltage will each of Q1: and Q2: be operating when vid = 0? If vid for full current switching is to be 0.5 V, what must the bias current I be changed to?
