Abstract

A current-controlled oscillator includes a plurality of switches for generating a time delay signal, each switch including an MOS transistor operatively coupled to the next gate by means including a capacitor, the final MOS transistor being connected to the initial MOS transistor by a feedback conductor also operatively connected with a capacitor. The frequency of the oscillator is varied by varying current injected into the oscillator.
