Abstract
A method for regulating the duty cycle of an input clock signal includes producing a second clock signal using a first adjustable delay circuit for varying the duty cycle. The second clock signal is applied to first and second circuits for respectively increasing and decreasing the duty cycle of the second clock signal. The method further includes monitoring if the first circuitry increases the duty cycle or if the second circuitry reducing the duty cycle saturates first. The duty cycle introduced by the first adjustable delay circuit is modified until saturation of the first and second circuits occur at substantially the same time.
