Abstract
A high speed CMOS NOR gate employs a pair of cross-coupled inverters and a dual set of N-channel pulldown transistors (202, 203) at each of the nodes between the two inverters, together with small pullup transistor (205) on the output terminal that is permanently energized and a switchable large pullup transistor (220) that is a link between the second inverter output and the first inverter input.
