Low power one-shot boost circuit
This invention discloses a voltage boost circuit which comprise at least one capacitor with a first terminal connected to an output of the voltage boost circuit, a controllable switch connected between a second terminal of the capacitor and a voltage source, the second terminal being different from the first terminal, and a voltage level detector detecting the output voltage level of the voltage boost circuit and providing a control signal to the controllable switch, wherein when the output voltage exceeds a predetermined level the controllable switch is off, and when the output voltage is lower than the predetermined level the controllable switch is on.
