A SIGNAL OUTPUT APPARATUS, A CHARGE PUMP, A VOLTAGE DOUBLER AND A METHOD TO OUTPUT CURRENT

摘要

A signal output apparatus, a charge pump, a voltage doubler and a method to output current. They use the interior circuit of a chip to generate an oscillation signal whose swing is between 0 and 2 × V IN , and use it to drive a charge pump type voltage doubler which uses a large capacitor outside the chip to output a large current.
