Abstract
Abstract A power booster circuit is described. The booster circuit having amplifying circuitry comprises an input circuit, a switching circuit, and an auxiliary power circuit. The booster circuit is initiated by receipt of a signal by the input circuit. The amplifying circuit latches on when initiated by the switching circuit. The amplifying circuit produces a constant boosted power signal, using an auxiliary power circuit.
