Abstract
An A/D converter includes: a sampler that includes a sampling capacitor and samples an input signal; a D/A converter that selectively outputs an analog voltage; an integrator that integrates an input from the sampler and an input from the D/A converter; Multiple switches that include a first switch independently connecting the sampler to the integrator, a second switch independently connecting the D/A converter to the integrator, a third switch, and, a fourth switch, a quantizer that quantizes an output of the integrator; a control circuit that outputs a digital value based on an output of the quantizer, and a reference potential generation circuit that provides a second reference potential to an integrator side of the sampler through the third switch and provides a first reference potential to the integrator side of the D/A converter through the fourth switch.
