Basic Operation of the SAR ADC. The basic successive approximation register analog-to-digital converter is shown in the schematic below: SAR ADC takes “snapshots” Each conversion command captures the signal level, at that point in time, onto the sample/hold 9 ADC calculates an average The signal is sampled continuously What is the ADC actually converting? SAR vs. Delta-Sigma SAR SAR ADC architecture. In order to improve the common mode noise suppression capability and conversion accuracy, the AD converter usually uses a differential structure.

In the project, a Charge redistribution DAC with binary weighted capacitance [3] configuration is used. In some previous articles general overviews of Δ-Σ and SAR (successive approximation register) ADCs, the techniques of oversampling as it relates to signal-to-noise ratio (SNR) and effective number of bits (ENOB) have been covered. The oversampling technique is most often used with the Δ-Σ ADC, but it is also useful with the SAR ADC. This is a particular type of Analog to Digital converter.

A SAR ADC uses a series of comparisons to determine each bit of the converted result. Therefore, a SAR ADC needs at least n+1 clock cycles to convert an analog input to the ADC to a result, where n is the number of bits of the ADC. How it Works. A low power differential self-calibrating 460 kS/s 16-bit rail-rail-input SAR A/D converter has been implemented in a 90-nm bulk CMOS technology using metal fringe capacitors.
