Abstract
A signal output apparatus, a charge pump, a voltage doubler and a method for outputting a current are provided. The interior circuit of a chip is used to generate an oscillation signal with a swing of 0 to 2×V, which drives a charge-pump type voltage doubler using large capacitors outside the chip to output a large current.
