Abstract
An A/D converter that supports multi-mode and that can minimize power consumption is provided. A hybrid A/D converter comprises: hybrid stages composed of 1.5-bit A/D converter for pipeline use that convert analogue input signals into digital signals; 1/1.5-bit D/A converters that switch between pipeline use and delta-sigma modulation use according to the mode in use; analogue adders that subtract output of the 1/1.5 D/A converters from the analogue input signals; and analogue operation circuits that receive as input the output of the analogue adders and function as amplifiers in pipeline mode and as integrators in delta-sigma mode.
