Abstract:
A circuit for generating multi-phase, non-overlapping clock signals includes a shift register that generates first and second clock signals from an input clock signal. First and second circuit modules generate corresponding first and second interim signals using the first and second clock signals and first and second feedback signals, respectively. The first and second interim signals are non-overlapping by at least a predetermined minimum time difference. The first and second interim signals are multiplexed to generate an output signal. The output signal is delayed by a first predetermined time to generate a first delay signal. The first delay signal is delayed by a second predetermined time to generate a second delay signal. The second delay signal is de-multiplexed to generate the first and the second feedback signals, and the first delay signal is de-multiplexed to generate the set of multi-phase, non-overlapping clock signals.
