ABSTRACT:
A CMOS driver with minimum shoot-through current is disclosed. The potential for shoot-through current may be eliminated or reduced with a break-before-make circuit driving an output stage. The break-before-make circuit may include a first logic element followed by a first inverter and a second logic element followed by a second inverter. The inverters may be cross-coupled to one another and/or the internal transistors may be configured with different strengths. The logic elements may be configured to eliminate or reduce potential shoot-through current paths, and the signal inputs may be controlled within a certain voltage range.
