ABSTRACT:
A multi-stage Successive Approximation Register Analog-to-Digital Converter (SAR ADC) and an analog-to-digital converting method using the same are provided. The multi-stage SAR ADC connects small-size and low-power SAR ADCs in multiple stages, thereby reducing a whole chip size and power consumption. The analog-to-digital converting method simultaneously performs analog-to-digital conversions in the SAR ADCs connected in the multiple stages, thereby reducing an analog-to-digital conversion time and maintaining an operating rate of several tens of MHz to several hundreds of MHz similar to that of a pipeline ADC.
