Abstract
An amplifier circuit has a sampling circuit to comprise a sampling capacitor which samples an input voltage and a plurality of switches, a quantizer to quantize an output voltage of the sampling circuit, a DA converter to output an analog signal depending on a quantization signal by the quantizer, and a feedback capacitor to feed the analog signal back to the output voltage of the sampling circuit.
