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. The comparator is used to determine the state of the current bit.

In simple word, ADC acts as A design of a 10-bit 25 MS/s Successive Approximation Register (SAR) Analog to Digital Converter (ADC) that uses improved dynamic comparator has been The proposed SAR ADC architecture is designed using CMOS 0.35µm technology with voltage supply of 3.3V. Cadence Design Systems was used for the circuit The optimal design of SAR ADCs requires the accurate estimate of nonlinearity and parasitic capacitance effects in the feedback charge redistribution DAC. instrument to assist the design of a charge redistribution SAR. ADC and predict its static and dynamic metrics. Keywords—Analog-to-digital conversion, assisted Although it is somewhat process-and-design-dependent, component matching limits the linearity to about 12 bits in practical DAC designs. Many SAR ADCs use a The consumptions of the capacitive digital-to-a converter (DAC), latch comparator , and digital c circuit of the proposed ADC are lower than thos conventional SAR This example shows how to design a SAR ADC using reference architecture and validate the ADC using ADC Testbench. This article presents a method of developing and debugging algorithms for mixed -signal schemes using mathematical model. SAR ADC is used as an example Concept and Design of a High Speed Current Mode Based SAR ADC [Elkafrawy, Abdelrahman, Ortmanns, Maurits] on Amazon.com.

SAR ADCs have a decent conversion speed (about 50kHz to 4MHz [13]) and take small overall chip area in comparison to flash ADCs, which are fast but take up a large area. SAR ADC design also flows well with the use of a serial output port due to … Abstract.

Figure 2. SAR operation (4-bit ADC example). Notice that four comparison periods are required for a 4-bit ADC. Generally speaking, an N-bit SAR ADC will require N comparison periods and will not be ready for the next conversion until the current one is complete.
