Abstract
A signal generator includes a frequency divider having an input node for receiving a first signal having a first frequency f.sub.1 and a single output node for outputting a second signal having a second frequency f.sub.2, wherein a ratio f.sub.1 /f.sub.2 is equal to an odd number that is equal to or greater than three. A synchronous delay circuit has an input node coupled to the single output node of the frequency divider and an output node for outputting a third signal that is delayed in time with respect to the second signal by an amount that is a function of a period of the first signal. Logic is provided having a first input node coupled to the single output node of the frequency divider and a second input node coupled to the output node of the delay circuit. The logic has an output node for outputting a fourth signal having the second frequency f.sub.2 and a 50% duty cycle. In a further embodiment the signal generator outputs a frequency that is (2n+1)/2 of the input frequency, where n any positive integer.
