Abstract
A low current single chip oscillator timing circuit which includes a dual mode capacitor circuit having a larger capacitance mode and a smaller capacitance mode having a fixed ratio. The timing circuit also includes an oscillator circuit that uses the dual mode capacitor circuit as a part of its time base wherein the large capacitance mode is operated with low power consumption and as needed includes a circuit that generates a reference pulse, wherein the short pulse and the reference pulse are compared and the result is used for correction to the oscillator frequency to create a feedback loop.
