Abstract
A circuit for reducing and offsetting the voltage swing of a differential pre-drive circuit. The circuit includes a first H-bridge of transistors receiving a differential pair of input signals. A swing resister is coupled to the H-bridge for reducing a voltage swing of the differential pair of input signals. The reduced swing is generated as a differential pair of output signals. Also, the differential pre-drive circuit includes an offset resistor that is coupled to the H-bridge. The offset resistor acts to offset the differential pair of output signals. As such, the differential pair of output signals having reduced swing and offset as applied to gates of output transistors in an output stage allow the output transistors to remain in the saturation operating state.
