<p>There is disclosed a self-regulating clock generator for providing an output clock signal to clock a CMOS microprocessor. The output clock signal has first and second phases of sufficient length to accommodate microprocessor speed paths and is provided in response to an input clock signal having a frequency and a duty cycle within a wide range of frequencies and duty cycles. The clock generator includes a latch arranged to be set and reset by the input clock signal and having an output for providing the output clock signal. A delay circuit is coupled to the latch output and enables the setting and resetting of the latch to establish the phase lengths. Also disclosed is a second clock generator which includes a pair of latches and a pair of delay circuits for providing an output clock signal having first and second phases of different lengths.</p>
