Re: Comparator design
Hi dedalus,
let me clear what you say. If we make the cross coupled devices the same size as diode connected load then we should not see any hysteresis provided we set the DC sweep interval very small like 1e-3. right?
I also observed another thing that if we make our cross coupled devices smaller than diode connected ones then in the transient simulation comparator works perfectly and its response time improves as we reduce further and further the size of cross coupled as compared to diode connected devices. Do you see it is possible or it is also again due to less resolution of transient simulations. I wanna reduce the response time, is there other things i can try. I have already pushed input diff pair to their limit.
