thank for ur reply, ..but
i asked about how to calculate differential gain for a fully differential opamp because when we do ac analysis we get single ended gain . but same procedure done for diff gain it gives gain in "-"dB's (not correct ...
)...so how to get the differential gain of opamp??is it just addition of two gain on single ended or single ended gain is only differential gain??
