Based on the application and designed task for implant of sensors or chips, integrated circuit (IC) designers tend to propose a unique SAR design both in architecture and circuitry. This is exactly what has been done in this thesis. This work is based on the Introduction to SAR (Successive Approximation Register) ADC analog input model, kickback, and RC filter.Try the Precision ADC Driver Tool: https://goo.gl/Cq5 Se hela listan på element14.com 08368773_A Low-Power and Performance-Efficient SAR ADC Design.pdf.

16-bit resolution, C total ~100pF for reasonable kT/C noise contribution 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. 3 SAR ADC Design (5) Targeting the Test and Measurement application, this section includes many topics relevant to designing with SAR ADC devices.

The S/H circuit captures the input analog signal based on a sampling frequency. In the project, the sampling frequency is 200 KHz. As a result, outstanding conversion linearity, high signal-to-noise ratio (SNR), high conversion speed, robustness, superb energy efficiency, and minimal chip-area are accomplished simultaneously. The first design is a 12-bit 22.5/45-MS/s SAR ADC in 0.13-μm CMOS process.
The SAR architecture allows for high-performance, low-power ADCs to be packaged in small form factors for today's demanding applications. This paper will explain how the SAR ADC operates by using a binary search algorithm to converge on the input signal. It also explains the heart of the SAR ADC, the capacitive DAC, and the high-speed comparator.
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. IV. CHIP MEASUREMENT RESULTS As a proof of concept, a prototype 1st-order NS SAR ADC is fabricated in a 0.13 m CMOS process.

This paper presents a passive-charge-sharing successive approximation register (SAR) analog-to-digital converter (ADC) that achieves 16-bit linearity. It is known that on-chip passive charge sharing suffers from poor linearity due to the unregulated reference voltage during bit trials. This paper gives a detailed analysis for the reasons of poor linearity for passive-charge-sharing SAR ADCs
As shown in Figure 1, SAR ADC is consisted of the sample and hold circuit, comparator, DAC and digital. Jul 20, 2016 Remarkable improvements have been recently reported on single-channel time- interleaved charge-based SAR ADCs to achieve sampling The single-channel SAR ADC adopts asynchronous processing with two alternate comparators.
