Gaurav Agrawal wins IEEE SSCS 2020-2021 International Student Circuit Contest
 
 

Gaurav is one of the two winners of 2020-21 International Student Circuit Contest by IEEE Solid-state Circuits society. Gaurav solved the problem below:
Provide an example of an amplifier where, despite the presence of a positive feedback, the system cannot latch since the topology guarantees always a positive gain margin (regardless the components values or mismatches)? In your answer please clarify the expression of the loop gain and show that there is actually a positive feedback but the magnitude can never exceed one.
