In this paper, a high speed low power 2b/cycle successive approximation register (SAR) analog-To-digital converter (ADC) is proposed for medical imaging. The ADC adopts a two-stage differential pair based interpolation technique that can reduce resolution of the capacitive DAC and avoid usage of sma...
