Abstract

See full text

Systems and methods are provided for a clock generator is configured to generate N clock signals evenly spaced by phase. A clock generator includes a poly phase filter configured to utilize a differential clock signal to generate N intermediate signals, the intermediate signals being spaced approximately 360/N degrees apart in phase. A phase error corrector is configured to receive the intermediate signals and to generate N clock output signals, where a phase error is a measure of a difference in phase between consecutive ones of the clock output signals from 360/N degrees, the phase error corrector being configured to reduce phase error among the clock output signals based on a feedback signal. A phase error detection circuit is configured to receive the clock output signals and to generate the feedback signal based on detected phase errors among the clock output signals.
