Abstract
A BiCMOS output driver in which a bipolar device is driven by a control signal that biases the collector of an NFET. The control signal enables the bipolar to pull an output node to full potential (ground) quickly. The signal then falls within one nanosecond after the output reaches ground, pulling the bipolar out of saturation. A separate feedback device coupled between the base of the bipolar and ground can be added to pull the bipolar out of saturation before the control signal falls.
