Semiconductor device

Abstract

A semiconductor device includes an amplifier circuit including an output terminal and an input terminal coupled to a detection element; an arithmetic circuit coupled to the output terminal of the amplifier circuit; and a control circuit coupled to an output side of the arithmetic circuit. The control circuit is configured to control the amplifier circuit while repeating a control period, switch between a first operating state in which the amplifier circuit outputs an offset voltage, and a second operating state in which the amplifier circuit outputs a voltage obtained by amplifying a voltage input to the input terminal; and perform, within the control period, an operation through the arithmetic circuit after switching the amplifier circuit between the first operating state and the second operating state.
