Abstract

See full text

An analog-to-digital conversion device is provided that includes a front SAR ADC and a plurality of rear SAR ADCs. The front SAR ADC is configured to convert an analog input signal into a group of higher bits of a digital output signal in response to different time periods. Each of the rear SAR ADCs is electrically coupled to the front SAR ADC and is configured to receive the analog input signal and the corresponding group of higher bits in response to the different time periods. The rear SAR ADCs convert the analog input signal into a group of lower bits of the digital output signal corresponding to the time period of the group of higher bits.
