Title: TIME-TO-DIGITAL CONVERTER, DIGITAL PHASE-LOCKED LOOP, METHOD FOR OPERATING A TIME-TO-DIGITAL CONVERTER, AND METHOD FOR A DIGITAL PHASE-LOCKED LOOP
Abstract:
A time-to-digital converter is provided. The time-to-digital converter includes a delay circuit configured to iteratively delay a reference signal for generating a plurality of delayed reference signals. Further, the time-to-digital converter includes a plurality of sample circuits each configured to sample an oscillation signal based on one of the plurality of delayed reference signals. The time-to-digital converter additionally includes a control circuit configured to de-activate at least one of the plurality of sample circuits based on a predicted value of the phase of the oscillation signal.
