DESIGNOF!A! SUCCESSIVEAPPROXIMATION(SAR)!ADC! IN65nmTECHNOLOGY sar adcs Successive-approximation-register (SAR) analog-to-digital converters (ADCs) are the workhorse products of the industry because they offer good resolution at high sampling rates. Maxim SAR ADCs offer some of the lowest power specifications in the industry while also offering accuracy specifications that are close to those provided by more expensive sigma-delta ADC's. SAR ADC without significant modification to the basic SAR ADC structure [10]. The rest of the paper is divided as follows. Section II and Section III examine the energy efficiency of charge-redistribution SAR ADCs.

The SAR ADC 1 is an n-bit ADC comprising a sample and hold (S&H) block 2, a comparator 3, a control block 4, an n-bit DAC 5, a first input/output (I/O) 6, and a second input/output 7. The SAR ADC 1 The SAR ADC has an internal DAC, which at every clock converts the 8-bit SAR Logic output into discrete signal, which is fed into the comparator. This feedback is used to decide the next bit of the SAR output.
