Abstract
A quantization circuit includes a quantizer and a compensation circuit. The quantizer includes a voltage-to-phase converter and a phase difference digitization block. The voltage-to-phase converter is arranged for generating a phase signal according to an input voltage. The phase difference digitization block is arranged for generating a quantization output according to a phase difference between a phase of the phase signal and a reference phase input. The compensation circuit is arranged for applying compensation to the phase difference digitization block according to the quantization output.
