Abstract
A method and apparatus for efficiently powering an integrated circuit include processing that begins by generating a representation of a battery voltage. The processing then continues by producing a regulated bias current based on the representation of the battery voltage. The processing continues by providing the regulated bias current to an external crystal, which, in turn, generates an oscillation in response to the bias current. The processing then continues by generating a clock signal from the oscillation produced by the external crystal. The clock signal is then provided to a DC-to-DC converter that converts the battery voltage into a regulated output voltage.
