Abstract

Official abstract text for this publication.

An analog-to-digital conversion device has: an analog-to-digital converter configured to receive an input signal via an input signal node, and convert the input signal to a digital signal; and a control circuit configured to receive the digital signal when the input signal is set to have a fixed value, and change, when a deviation amount of the digital signal with the respect to an expected value is equal to or larger than a threshold value, a value of a capacitor between a power supply potential node and a reference potential node of the analog-to-digital converter and/or values of resistors connected to the power supply potential node and the reference potential node of the analog-to-digital converter.

First claim

Opening claim text (preview).

What is claimed is: 1. An analog-to-digital conversion device, comprising: an analog-to-digital converter configured to receive an input signal via an input signal node, and convert the input signal to a digital signal; and a control circuit configured to receive the digital signal when the input signal is set to have a fixed value, and change, when a deviation amount of the digital signal with respect to an expected value is equal to or larger than a threshold value, a value of…
