Analog-to-digital conversion circuit, analog-to-digital conversion device, and digital x-ray imaging system

Abstract

Disclosed are an analog-to-digital conversion circuit, an analog-to-digital conversion device, and a digital x-ray imaging system. The analog-to-digital conversion circuit includes a first reference voltage source, a second reference voltage source, a first analog-to-digital converter connected to the first reference voltage source, a second analog-to-digital converter connected to the second reference voltage source, a connecting circuit connected to the first analog-to-digital converter and the second analog-to-digital converter, respectively, and a current source having negative temperature coefficient configured to be connected to the first reference voltage source and the second reference voltage source, respectively.

Dependencies are inferred from the claim text.
