I came across this question in "fundamentals of microelectronics" The objective is to find out the polarity of the feedback. Could someone help me with this?
My approach to this question is as follows:
If we increase input current then the voltage at point x increases due to which the drain current of M1 increases causing a decrease in the Vout.This in turn decreases the drain current of M2 causing an decrease in the voltage at point x.Therefore the feedback is negative. Is this approach correct?
