Operational amplifier with high gain and symmetrical output-current capability |
摘要 |
An operational amplifier includes a first stage, and a second stage with an input connected to an output of the first stage and an output connected to a load. The second stage includes between its input and its output a first signal path for driving the load in a first direction, and a second signal path for driving the load in the opposite direction. The first and second signal paths have substantially equal gains for small signals, substantially equal output impedances for small and large signals, and substantially equal output-current capabilities.
