Abstract:
A multiple-phase clock generator includes at least one stage of dividers. A clock signal is supplied as a first stage clock input to dividers in a first stage of dividers. An N-th stage includes 2N dividers, where N is a positive integer number. Each divider in the first stage is configured to divide a first clock frequency of the first stage clock input by 2 to provide a first stage output. Each divider in the N-th stage is configured to divide an N-th clock frequency of an N-th stage clock input by 2 to provide an N-th stage output. The N-th stage outputs from the dividers in the N-th stage provide 2N-phase clock signals that are equally distributed with a same phase difference between adjacent phase clock signals.
