So this is how we design our SAR-ADC circuit from beginning to end. We will first determine what our input signal looks like in terms of the bandwidth and a full-scale range. Once we understand the characteristics of our input signal, we will take a look at the ADC. The ADC that we select should match the bandwidth of our input signal per nyquist.

The main features of the Successive Approximation (SAR) ADC architecture de- This SAR ADC is designed based on common-mode voltage V cm with a tri-level switching method. Compare with the traditional structure, it only uses half of the unit capacitors. It can save a large proportion of switching energy consumption, the most significant bit (MSB) conversion without drawing any energy, and tri-level switch changing from common-mode voltage V cm to the reference voltage V The successive approximation register analog to digital converter (SAR ADC) technique is not yet mature in China mainly because of the imperfect analog module of the SAR ADC. The purpose of this design was to optimize the analog module by designing and making a 8-bit 1MHz SAR ADC and testing a 12-bit SAR ADC theoretically and by simulation. The design of the 1MHz SAR DAC, which consists of Introduction to SAR (Successive Approximation Register) ADC analog input model, kickback, and RC filter.Try the Precision ADC Driver Tool: https://goo.gl/Cq5 This video is about Successive Approximation ADC taped out as part of the VLSI design course project. 2017-07-20 digital domain. In this design, we reconﬁgure the NS ADC in the conventional Nyquist SAR mode at ﬁrst and apply classic foreground calibration techniques [7] to estimate the DAC mismatch errors.
