Abstract

A multi-channel integrator includes a first switch, a second switch, and a plurality of integration units. First terminals of the first and second switches receive a first reference voltage. Each of the integration units includes an operational amplifier (OP-AMP), a feedback switch, a third switch, a fourth switch, and a feedback capacitor. A second input terminal of the OP-AMP receives a second reference voltage. Two terminals of the feedback switch are respectively coupled to a first input terminal and an output terminal of the OP-AMP. First terminals of the third switch and the fourth switch are respectively coupled to the first input terminal and the output terminal of the OP-AMP. A first terminal of the feedback capacitor is coupled to the second terminals of the first and the third switches. A second terminal of the feedback capacitor is coupled to the second terminals of the second and the fourth switches.
