Hi,
I want to simulate with Hspice, the fully differential OTA such as, AC gain and phase margin. Generall speaking, fully differential amplifier has two input vin+/vin-, two outputs vout+/vout- .
I know the differential mode gain is Av=(vout+ - vout-)/(vin+ - vin-).
But How I do this in the Hspice.
Regards
