Abstract
An analog-to-digital converter includes a switched capacitor circuit, an analog-to-digital conversion circuit, and a constant current circuit. The switched capacitor circuit includes first and second input terminals for a differential input, and is configured to sample an analog voltage of the differential input. The analog-to-digital conversion circuit is connected to output terminals of the switched capacitor circuit, and configured to convert the sampled analog voltage into a digital signal and output the digital signal. The constant current circuit is connected to at least one of the first and second input terminals.
