Abstract
A circuit that provides a stable predrive to a BiCMOS LVDS output which compensates for supply voltage variations while maintaining a suitably fast signal path. The supply voltage compensation circuit provides an offset to the predrive level shift such that when the supply voltage Vcc rises, the predrive output voltage is lowered in response.
