Abstract
A delta-sigma modulator includes a capacitively-coupled amplifier, a first integrator, a second integrator, a quantizer, a first switch, a second switch, and a control circuit. The first switch is connected between an input of the capacitively-coupled amplifier and a sampling capacitor of the capacitively-coupled amplifier to execute a chopping operation. The second switch is connected between an output of the capacitively-coupled amplifier and an input of the first integrator to execute a chopping operation. The control circuit executes modulation through the first switch at the input of the capacitively-coupled amplifier, executes demodulation through the second switch at the output of the capacitively-coupled amplifier, and imports an output signal of the capacitively-coupled amplifier into the first integrator after the demodulation.
