Abstract
An MOS oscillator circuit which is relatively immune to power variations in the supply is presented. A capacitor is charged and discharged in responsive to the feedback signal from a Schmitt trigger circuit. The current to charge and discharge the capacitor is generated by a current mirror which is regulated by a constant voltage generator for immunity from power supply variations.
