Noise-shaping circuit, digital-to-time converter, analog-to-digital converter, digital-to-analog converter frequency synthesizer, transmitter, receiver, transceiver, method for shaping noise in an input signal

摘要

A noise shaping circuit according to an example includes a forward signal path configured to generate an output signal based on an input signal, a feedback signal path configured to feed back a feedback signal based on the output signal to the forward signal path, and a dither generator configured to generate a dither signal and to couple the dither signal into the forward signal path to modify the input signal and into the feedback signal path. Employing a noise shaping circuit according to an example may improve an overall noise performance.
