ABSTRACT:
An operational amplifier (10) is provided which includes a differential input stage (18) for receiving differential signals. A differential loop (30, 64), (86) amplifies said differential signals. The amplified differential signals are output on a pair differential output terminals (80, 84). A common mode loop (54), (30, 64) maintains the mean voltage of the amplified differential signals at a preselected value.
