- CMOS SAR ADCSUCCESSIVE APPROXIMATION REGISTER ANALOG DIGITAL CONVERTER AND CMOS IMAGE SENSOR COMPRISING THE SAME

摘要

According to an embodiment of the present invention, a successive approximation register analog digital converter (SAR ADC) comprises: a digital-analog conversion unit for receiving N (N is a natural number) number of digital bits and outputting a first analog voltage through second and third sub digital-analog converters respectively including a plurality of capacitors and resistances; and an SAR unit for determining the N number of digital bits by receiving a result of comparing the first and second analog voltages.
