发明名称 D/A変換器及びD/A変換器の制御方法
摘要 The present invention relates to a control method of a D/A converter, a D/A converter, a control method of an A/D converter, and an A/D converter that can suppress an existing n-th harmonic without using a large-scale circuit, such as a bootstrap. A D/A converter (10) of the present invention is a D/A converter (10) that can suppress the generation of an existing n-th harmonic (n is an integer of 2 or more) of an analog output signal. The D/A converter (10) includes a D/A conversion unit (11) that converts an input digital signal into an analog signal and a control unit (12) that arbitrarily controls the timing of the sampling phase and the integral phase of the D/A conversion unit (11). The D/A conversion unit (11) is configured to generate an arbitrary n-th harmonic and superimpose the arbitrary n-th harmonic on an analog output signal including the existing n-th harmonic.
