This paper gives a detailed analysis for the reasons of poor linearity for passive-charge-sharing SAR ADCs 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. The main target is to design an ultra-low power 10-bit SAR ADC operating at f s = 1kS/s. 1.3 Thesis outline In this thesis, Chapter 2 reviews the fundamentals of A/D conversion and performance metrics of A/D converter. Chapter 3 presents the different architectures of SAR ADC and introduces sub-modules of the SAR ADC. ubiquitous SAR ADC architecture and design can be used in all medical chips and devices.

The S/H circuit captures the input analog signal based on a sampling frequency. In the project, the sampling frequency is 200 KHz. SAR ADC V IN n C LK r V F e d C • Any DAC structure can be used • In basic structure, single comparator can be used • Performance entirely determined by S/H, DAC, and comparator • Very simple structure and relatively fast design procedure • If offset voltage of comparator is fixed, comparator offset will not introduce any nonlinearity Se hela listan på Technical Article Learn About SAR ADCs: Architecture, Applications, and Support Circuitry October 24, 2019 by Steve Arar In this article, we’ll first review the basic architecture of a SAR ADC and then take a look at one of its common applications. 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.

Since the proposed design was made completely differential and hence reduced the noise parameter SNDR significantly. 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 SAR ADC Input Driver Design.
