Abstract
An amplifier having an imbalance between pull-up and pull-down sections may include a counterpart section to balance the output sections and/or enable them to be driven by balanced drive signals. In one embodiment, a rail-to-rail output stage may include a current minor to drive one side of the circuit. The other side may be driven by a transistor having a counterpart transistor to balance the circuit. A drive section may include a balance point to facilitate balancing the drive signals.
