Abstract
An oscillator circuit capable of being fully implemented in integrated circuit form and having a first current source for charging a first capacitor so as to produce a time varying voltage which is sensed by a first comparator when the voltage reaches a predetermined threshold level. The circuit further includes a second current source for charging a second capacitor so as to produce a further time varying voltage which is sensed by a second comparator when the voltage reaches the predetermined threshold voltage. The output of first and second comparators are combined so as to produce the output clock signal, with the first cycle segment of the clock having a duration determined by the first comparator output and the second cycle segment of the clock having a duration determined by the second comparator output.
