Abstract
A duty-cycle regulation method for deriving an output clock signal having a predetermined duty cycle from an input clock signal having an arbitrary duty cycle. Once the input clock signal is received, an output clock storage element is switched to a first state upon detecting a transition in the input clock signal for driving the output clock signal to a first signal level. The output clock storage element is then switched to a second state after a delay interval equal to a fraction of the period for driving the output clock signal to a second signal level. The fraction of the period can be programmed to a pre-selected value.
