hi, i have designed a two stage op amp with 1v supply in 65nm tech. input common mode voltage=0.4 to 0.7 output bias point =0.5(swings from .2 to .9 ) now i connected in non inverting configuration with gain 3 then it is saturating because of output swing limitation(actually op amp trying to go 1.2 because non inverting input i gave .4 as bias ) means op amp is trying to amplify both signal as well as bias. Is there any method to subtract bias voltage in the feed back so that we can get wide range of gains thanks
