Hi,
I have a question about sense amplifier simulation. I want to know how much gain I get from my sense amplifer. I did AC analysis for an Op design before and I applied the same way I did with the Op to my sense amplifer. In other words, I set Vcm+small signal, Vcm-small signal and then look at the output. However I got a number in the range of negative dB, which is very very small. Actually, the input pairs and the nmos at the bottom end are all in triode region. Can anybody point out any mistakes I've made?
