ABSTRACT:
An oscillator circuit which demonstrates stable operation over a wide range of supply voltages and process variations. A latch circuit is controlled utilizing a timing capacitor. A constant current source is applied alternately to opposite sides of the timing capacitor through a series of switching gates which bootstrap the voltage across the timing capacitor, with the switching gates being controlled by the output of the latch circuit.
