Abstract
A new SARADC has two low resolution SAR (Successive Approximation Register) ADCs coupled together by an amplifier to increase the overall resolution and enhance ADC conversion rate. The gain reduction of amplifier is corrected by shifting the digital binary output position. Two SAR ADC outputs are timing aligned and summed to produce final high-resolution high conversion rate ADC output.
