Abstract: A system includes a mixer of a phase interpolator. The mixer includes a dynamic load whose output signal is coupled to a subsequent stage of the phase interpolator. The dynamic load is configured to provide an alternating current (AC) signal to the subsequent stage of the phase interpolator as input clock signals. The mixer further includes a static load whose output signal is coupled to the subsequent stage of the phase interpolator in parallel with the respective output signal line of the dynamic load. The static load configured to provide a direct current (DC) signal to the phase interpolator temporarily in replacement of the respective AC signals to prevent output signals of the subsequent stage of the phase interpolator from being unpredictable.
