Abstract :
The side effect of the anti-backlash delay in digital phase-frequency detector is analyzed. It is shown that the frequency tracking ability of the detector is decreased by the delay, so that the lock-in transition time will increase. Furthermore, it is shown that the side effect is mainly caused by the delay to the front edge of the reset pulse. Both computer simulation and experimental verification shows the analysis is correct. The work gives an insight view of the detector´s working principle and will be useful for its design.
