ABSTRACT:
A delay circuit for differential signals has input terminals for receiving primary and complementary phases of the differential signals and output terminals upon which the primary and complementary phases of output differential signals are generated after a suitable delay. A differential comparator controls charging and discharging of first and second capacitors, one capacitor being provided for each phase for providing a seleced delay. The time difference between switching of the differential comparator and the subsequent voltage level transistion of the relative charges on the first and second capacitors determines the time delay dt. The delay circuit is compensated for power supply and temperature variation.
