ABSTRACT:
A signal-delaying capacitive circuit applied to a node in a microcircuit device is immunized against the variation of the supply voltage by a metal-oxide semiconductor connected in series between the node and the signal-delaying capacitive circuit. The gate of tile semiconductor is biased with a voltage signal proportional to the supply voltage, whereby the resistance of the semiconductor is increased as the supply voltage decreases; thus, isolating the capacitive circuit from the node and reducing the delay.
