The successive approximation ADC mainly includes a sample and hold circuit, a. DAC, a comparator, a clock circuit, and a SAR register. The rationality is verified

Translated documents are for reference only. SAR ADC is scalable with the technology scaling since most parts of the architecture apart from the comparator are digital. In this thesis, different structures of SAR control logics and dynamic latched comparators are studied; then, a 10-bit SAR ADC is designed and implemented in 65nm CMOS technology. Successive approximation register (SAR) converters offer a compact and power efficient alternative but the conversion speed is typically designed for lower frequencies. In this thesis a low-power 12-bit 200 MSps SAR ADC based on charge redistribution was designed for a 28 nm CMOS technology.

Resolution for SAR ADCs most commonly ranges from 8 to 16 bits, and they provide low power consumption as well as a small form factor. External SAR ADC

This feedback is used to decide the next bit of the SAR output. In the project, a Charge redistribution DAC with binary weighted capacitance [3] configuration is used.

29 okt. 2020 — In this thesis, the development of a SAR ADC in a 28-nm CMOS technology based on charge redistribution is presented.The implemented SAR

This paper will explain how the SAR ADC operates by using a binary search algorithm to converge on the input signal. The SAR ADC is one of the most intuitive analog-to-digital converters to understand and once we know how this type of ADC works, it becomes apparent where its strengths and weaknesses lie. Basic Operation of the SAR ADC. The basic successive approximation register analog-to-digital converter is shown in the schematic below: SAR ADC takes “snapshots” Each conversion command captures the signal level, at that point in time, onto the sample/hold 9 ADC calculates an average The signal is sampled continuously What is the ADC actually converting?
