Abstract:
An analog-to digital (AD) conversion circuit includes a digital-to-analog (DA) conversion circuit, an arithmetic circuit, and a comparison circuit. The DA conversion circuit generates a first reference current signal. The arithmetic circuit is electrically connected to the DA conversion circuit and generates a comparison current signal by adding the first reference current signal to a first current signal generated in accordance with a first voltage signal or subtracting the first reference current signal from the first current signal. The comparison circuit is electrically connected to the arithmetic circuit and outputs digital data based on a result of comparing a second current signal according to a second voltage signal with the comparison current signal.

Claim (Index 2):
