Low power voltage boost circuits.

摘要

A voltage boost circuit is provided for amplifying or boosting an input voltage to a higher voltage level while also providing a regulated voltage amount for the boosted output. The voltage boost circuit with regulated output is well suited for low power applications by providing an oscillator which can be switched between normal mode and standby mode of operation depending upon the voltage state of the amplified output. Once the voltage state is at or within a regulated range, the oscillator can be placed in a standby state and the power consumption normally associated with amplifier or oscillator operation is considerably reduced. A voltage multiplier ensures that the output voltage is maintained over a fairly long period of time without requiring active refresh and power consumption normally associated therewith. <IMAGE>
