1. A method comprising:
- testing a duty cycle of a random bit source;
varying an output voltage of a voltage source if the duty cycle has not substantially reached a first threshold; and
iteratively altering the output voltage of the voltage source until the duty cycle has not substantially reached the first threshold.

Abstract
A method of producing a uniform duty cycle output from a random bit source. The method includes testing the duty cycle of said random bit source; varying the output voltage of a voltage source if the duty cycle is not substantially fifty percent; and iteratively altering the output voltage of the voltage source until said duty cycle is substantially fifty percent.
