- A successive approximation resistor analog digital converter (SAR ADC) includes a first conversion unit including a correction capacitor array and a bit capacitor array 2V-1 less than the number of a bit, a second conversion unit configured to differentially operate with the first conversion unit, a comparator configured to output a voltage of a high level or a low level of each capacitor according to output voltages of the first and second conversion units, a successive approximation register (SAR) logic unit configured to receive an output voltage of the comparator to convert the received output voltage into a digital signal, and a correction logic unit configured to receive the digital signal converted by the SAR logic unit and to correct a digital signal of the bit capacitor array using a correction digital signal of the correction capacitor array of the received digital signal.
