ABSTRACT:
A high frequency driver circuit is described. The driver produces increased current flow at its output to decrease charging time, thereby enabling higher frequency operations. Increased current flow is achieved by providing an active control signal that increases the magnitude of the overdrive voltage applied to a driver transistor.
