Abstract
An enveloping curves generator is disclosed that guarantees that one curve will envelop or overlap another when both are traversing from one logic level to another, and where the other overlaps the first when both traversing the other direction. In one case, a steering FET controlled by an input signal drives a first output high via a circuit. That first output going high, after a delay, drives a second output high. When the input goes low, a second steering FET controlled by the input signal drives the second output low. That second output going low, after a delay, drives the first output low. No latching is provided in the present invention.
