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.

Abstract:
A temperature compensated crystal oscillator (10), has a crystal oscillator circuit (12), a voltage controlled reactance element (30), a temperature compensation network (50), and a programmable DC-DC converter network (60) having an output (62) connected to the voltage controlled reactance element (30), or the temperature compensation network (50) or both. The DC-DC converter network (60) provides the capability of operating over an extended voltage range, by increasing the supply voltage to a level necessary to operate the voltage controlled reactance element (30). Much of this structure is adapted for use in an integrated circuit, and provides the advantages of minimizing power and current consumption.
