Abstract

What is described is a high efficiency voltage doubler (100). The high efficiency voltage doubler (100), has a charge-pump capacitor (30), an inverter (18), a coupling capacitor (24), a complementary switch pair (16), a DC biasing circuit (102), a charging circuit (106), and an input circuit (108). This structure is adapted for use in an integrated circuit, and provides the advantage of maximizing voltage doubled power output and minimizing current consumption with a minimal number of components.
