Abstract
Disclosed is a successive-approximation register (SAR) analog-to-digital converter (ADC). The SAR ADC may include a capacitor-resistor hybrid digital-to-analog converter (DAC), and apply a low-power switching method and an input signal range scaling method to the DAC, thereby significantly reducing surface area and power consumption.
