User transparent self-calibration technique for pipelined ADC architecture US6958722B1 2005-10-25 SAR ADC providing digital codes with high accuracy

The SAR ADC is the commonly used architecture for data acquisition systems that are widely employed in medical imaging, industrial process control, and optical communication systems. In these applications, we usually need to digitize the data generated by a large number of sensors.

SAR ADC Considerations contd. •Comparator offset V os introduces an input-referred offset ~ (1+C P /ΣC j)*V os •C P in general has little effect on the conversion (V X→0 at the end of the search) •however, V X is always attenuated due to charge sharing of C P •Binary search is sensitive to intermediate errors made during search – Actually, the TI link describes the traditional approach in building integrated SAR ADC with charge redistribution. The ADI link is a bit fuzzy to me since it doesn't even give an idea what is inside the DAC block. Anyway, the comparator output is digital and it goes to the SAR logic.

This example shows how to design a SAR ADC using reference architecture and validate the ADC using ADC Testbench.

An SAR ADC is operated by sampling an input voltage and redistributing a corresponding charge among the coupling capacitor and a plurality of binarily weighted capacitors of a CDAC array to produce a first voltage on a charge summing conductor.

An ultra-low-power area-efficient 8-bit successive approximation register (SAR) analog-to-digital converter (ADC) is presented. To achieve ultra-low-power performance a DAC architecture is proposed that employs two rail-to-rail low-power unity-gain buffers and only 4 minimum-size capacitors instead of the conventional binary-weighted capacitor array.

SAR ADC Architecture. Although there are many variations in the implementation of a SAR ADC, the basic architecture is quite simple (see Figure 1). The analog input voltage (V IN) is held on a track/hold.

The residue is amplified and sampled by the second stage. SAR ADC Architecture. Although there are many variations in the implementation of a SAR ADC, the basic architecture is quite simple (see Figure 1).
