Hi Guys,
I have simulated a sample diff amp/op amp and found a difference of DC gain for various CM(common mode) voltage.
All transistor work in saturation region. If the variation is small(like a ±5dB) I will not concern and will think that is something technology dependence but it varies in ±15dB range.
Has someone experienced this kind of dependence????
Thanks.
