Abstract
Amplifier circuitry has sampling circuitry which samples an input voltage, a quantizer which quantizes an output voltage of the sampling circuitry and outputs an output code, a differential amplifier which amplifies a differential voltage between the output voltage of the sampling circuitry and a reference voltage and performs offset adjustment according to the output code of the quantizer, and a first capacitor which is connected between an output node of the differential amplifier and an output node of the sampling circuitry.
