Abstract :
A circuit using the properties of c.m.o.s. logic gates is described, which yields continuously variable delay over a range exceeding 3:1. Advantage is taken of the dependence of pulse transition time on supply voltage, and applications are suggested in digital transmission compensation as well as in the generation of variable frequency square waves.
