Abstract

A delta-sigma modulation type A/D converter includes: a capacitively coupled amplifier having a sampling capacitor, a feedback capacitor, and an amplifier; a correlated double sampling type first integrator as a first-stage integrator, which is connected to the capacitively coupled amplifier without a switch; a second integrator arranged after the first integrator; a quantizer arranged after the second integrator and quantizing an output of the second integrator; and an D/A converter that D/A-converts an output of the quantizer and feeds back to any one of the capacitively coupled amplifier, the first integrator, and the second integrator.
