Abstract:
A driver circuit includes a CMOS stage and switch functionalities for performing certain tasks. One task is to selectively block exposure of the CMOS stage to reference voltage(s). Another task is to selectively protect the CMOS stage during transient operation. Yet another task is to block leakage current from flowing from the CMOS stage to ground.
