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. In the project, a Charge redistribution DAC with binary weighted capacitance configuration is used.

SAR ADC Considerations •Power efficiency –only comparator consumes DC power •Conversion rate typically limited by finite bandwidth of RC network during sampling and bit-tests •For high resolution, the binary weighted capacitor array can become quite large •E.g. 16-bit resolution, C total ~100pF for reasonable kT/C noise contribution

With micro-controller interfacing in mind, the universal data transfer technique of SPI proved Successive-approximation ADC (SAR ADC) SAR ADC is one kind of ADC architecture which works on binary search method. Although it is much slower than other models like Pipeline and Flash ADC, power consumption is very low and a model of choice for low power devices. The working principle of SAR ADC seems reasonably complex, but not actually. International Journal of VLSI design & Communication Systems (VLSICS) Vol.6, No.3, June 2015 17 This paper describes design and implementation of 10-bit, 2MS/s split SAR ADC using 0.18um A successive-approximation ADC is a type of analog-to-digital converter that converts a continuous analog waveform into a discrete digital representation using a binary search through all possible quantization levels before finally converging upon a digital output for each conversion. Pipelined ADC Design - A Tutorial - Based on Slides from Dr. Bibhudatta Sahoo University of Illinois at Urbana-Champaign.

Transistor Level Design. The ADC consists of 5 major blocks - Sample/ Hold block, comparator, SAR Logic block, 8-bit DAC and the timing block. Each block is explained below. Sample/Hold Circuit. The S/H circuit captures the input analog signal based on a sampling frequency. In the project, the sampling frequency is 200 KHz.
