Abstract
An enveloping curve generator that guarantees one curve will overlap another when both are going high and the other overlaps the first when both are going low. When the input goes high, one steering FET is turned off and the other directs the input signal to drive an output high. That output going high after a delay drive the second output high. The second output being high latches the states of the two outputs high. When the input goes low, the off FET is turned on and the on FET is turned off. The input signal is directed to drive the second output low and after a delay the first output is driven low. The first output going low latches the states of the two outputs low.
