摘要： A high-order delta-sigma modulator is realized with amplifying/integrating circuits each having a small circuit scale, to thereby provide a small-size and low-power consumption delta-sigma modulator having a high precision. The delta-sigma modulator including the amplifying/integrating circuits connected in series in a plurality of stages has a delta-sigma modulator configuration in which one of adjacent amplifying/integrating circuits includes a delay integrating circuit and another thereof includes a non-delay integrating circuit. In an actual circuit, one amplifying circuit is operated in a time division manner to be shared between the adjacent amplifying/integrating circuits. The circuit scale is reduced in this way.
