Abstract
An improved circuit for providing a fixed reference voltage with a minimum consumption of power is provided. The circuit includes a fixed voltage element adapted to be referenced to a fixed voltage. A charge storage element is coupled in series with a uni-directional current gating element, the series coupled charge storage element and uni-directional current gating element being coupled in parallel with the fixed voltage element. A voltage supply intermittently applies a referencing voltage across the fixed voltage element to thereby intermittently charge the charge storage element to a fixed reference voltage for at least a predetermined period of time.
