Hi
I have simulated a simple dynamic comparator and it is working properly with input voltages beyond the supply rails, as I know we don't use input voltages beyond supply rails, Would you please explain why we cannot use inputs beyond the supply rails when the circuit is working properly?
Simulation below is for 0.9 v supply. One of the inputs is: 1.35 V fixed, and the other is a sine wave: 1.35+0.45sin(wt)
