The invention relates to a noise 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. 本公开涉及噪声整形电路、数字时间转换器、以及噪声整形方法。根据示例的噪声整形电路包括被配置为基于输入信号生成输出信号的前向信号路径；被配置为将基于所述输出信号的反馈信号反馈回所述前向信号路径的反馈信号路径；以及抖动生成器，该抖动生成器被配置为生成抖动信号并将所述抖动信号耦合到所述前向信号路径来修改所述输入信号以及将所述抖动信号耦合到所述反馈信号路径。采用根据示例的噪声整形电路可提升总体噪声性能。
