DELTA-SIGMA MODULATOR

摘要

A delta-sigma modulator is configured to feedback an output signal of a quantizer to an input of an integrator, and also feedback to the input of the integrator a differentiated error signal representing derivative of quantization error caused by the quantizer.

1. A delta-sigma modulator comprising:
an integration block configured to generate an integrated signal by integrating a signal including a first signal and a feedback signal; a quantization block configured to generate an output signal by quantizing the integrated signal; a differentiation block configured to generate a differentiated error signal representing derivative of quantization error caused by the quantization block; and a feedback path configured to provide the feedback signal including the output signal and the differentiated error signal to the integration block.
