Abstract:
An A/D converter includes a capacitor DAC, a resistor DAC, a first capacitive element, and a comparator. The capacitor DAC is configured to convert high-order M bits, where M and N are integers equal to or greater than 2, and the resistor DAC is configured to convert low-order N bits. The first capacitive element is provided between the capacitor DAC and the resistor DAC, and the comparator is configured to compare an input signal voltage with a voltage output from the capacitor DAC. The resistor DAC generates and outputs a voltage by adding or subtracting a wait based on redundant bits in addition to N-bit resolution.

Claim (Index 4):
The A/D converter according to  claim 3 , wherein\n the capacitor DAC comprises:\n a capacitor circuit including a plurality of capacitive elements configured to store electric charges by sampling the input signal voltage; \n a first switch circuit configured to select and apply one of a ground voltage or a reference voltage to one ends of the plurality of capacitive elements of the capacitor circuit, and wherein \n the resistor DAC comprises:\n a resistor circuit including a plurality of resistive elements configured to perform a resistance division among the ground voltage and the reference voltage; \n a second switch circuit configured to select and output a first voltage generated by a first resistance division of the resistor circuit; and \n a third switch circuit configured to select and output a second voltage generated by a second resistance division of the resistor circuit, wherein \n the first voltage is applied to other ends of the plurality of capacitive elements of the capacitor circuit through the first capacitive element.
