Abstract
A system and a method are disclosed for generating accurate and programmable phase delay output signals, including a phase detector unit configured to determine a phase disparity signal based on a phase error between outputs of a frequency divider unit cell; a digital calibration logic unit configured to generate a control signal based on the phase disparity signal; and a tunable delay lines unit configured to generate the phase delay output signals based on the control signal.
