SAR ADC Configuration: An SAR ADC is composed of a sample hold circuit, a comparator, a DAC, SAR logic circuit and timing generator (Fig.1).

The SAR ADC does the following things for each sample: The analog signal is sampled and held. For each bit, the SAR logic outputs a binary code to the DAC that is dependent on the current bit under scrutiny and the previous bits already approximated.

Reviews basic architecture, sparkle codes, metastability, and clock jitter. Shows trade-offs among different ADC designs. Design for 18-Bit SAR Data Converters Description This TI Design aims to improve the integration, power consumption, performance, and clock distribution typically associated with 18-bit SAR data acquisition (DAQ) systems. The analog front-end optimization is usually the most critical part of the ADC system signal path design. The key aspect of This example shows how to design a SAR ADC using reference architecture and validate the ADC using ADC Testbench.
