Abstract:
A ΔΣ modulator includes a first integrator which has first and second capacitors and integrates an analog input signal and a feedback analog signal, a second integrator which has third and fourth capacitors and integrates an output signal of the first integrator, a differential amplifier which has input and output terminals switched and connected via a switch circuit to either the first and second capacitors or the third and fourth capacitors, a chopper switch which switches the polarity of the input terminal and the polarity of the output terminal, to both of which the first capacitor and the second capacitor are connected, a quantizer which compares an added signal and a reference signal to output a digital value, and a digital/analog converter which outputs the feedback analog signal corresponding to the digital value.

Claim (Index 2):
A \u0394\u03a3 modulator comprising:\n a first integrator which has first and second capacitors and integrates an analog input signal and a feedback analog signal; \n a second integrator which has third and fourth capacitors and integrates an output signal of the first integrator; \n a differential amplifier which has input and output terminals switched and connected via a switch circuit to either the first and second capacitors or the third and fourth capacitors; \n a quantizer which compares a signal obtained by adding the analog input signal, the output signal of the first integrator, and an output signal of the second integrator and a reference signal to output a digital value; and \n a digital/analog converter which outputs the feedback analog signal according to the digital value provided from the quantizer, \n the differential amplifier including a chopper amplifier which switches a polarity of the input terminal and a polarity of the output terminal, said input and output terminals being connected with either the first and second capacitors or the third and fourth capacitors.
