Title:
ANALOG-DIGITAL CONVERTER, ELECTRONIC DEVICE, AND METHOD FOR CONTROLLING ANALOG-DIGITAL CONVERTER
Document Type and Number:
WIPO Patent Application WO/2018/047457
Kind Code:
A1
Abstract:
Power consumption is reduced in an ADC that performs AD conversion of single end signals. A pair of sampling capacitors samples the single end signals. When the single end signal is sampled, a connection control unit performs positive side connection control for connecting both ends of one of the pair of sampling capacitors between a positive side signal line and a prescribed reference potential, and negative side connection control for connecting both ends of the other of the pair of sampling capacitors between a negative side signal line and the prescribed reference potential. A conversion unit converts to digital signals the differential signals from the positive side signal line and the negative side signal line for which the positive side connection control and the negative side connection control were performed.
