for the FDA(fully differential OP-AMP) how to measure the gain and the phase, is it between for example the +vout and ground or +vout and -vout
regards
simply apply an ac source with unit amplitude between the in+ and in- terminals . then plot the gain and phase of the difference between out+ and out- .
