MODULATION CIRCUIT AND MODULATION METHOD WITH DIGITAL ELD COMPENSATION

摘要

A modulation circuit includes a digital quantizer and a compensation circuit. The digital quantizer is utilized to receive and truncate a digital quantizing input signal for generating a digital quantizing output signal. The compensation circuit compensates for a time delay of the modulation circuit and generates a compensation output signal. The digital quantizing input signal is generated by subtracting the compensation output signal from a digital integration output signal to compensate for the time delay before truncating the digital quantizing input signal.
