Understanding SAR ADCs - AN1080
ثبت نشده
چکیده
Successive-approximation-register (SAR) analog-to-digital converters (ADCs) are frequently the architecture of choice for medium-to-high-resolution applications with sample rates under 5 megasamples per second (Msps). SAR ADCs most commonly range in resolution from 8 to 16 bits and provide low power consumption as well as a small form factor. This combination makes them ideal for a wide variety of applications, such as portable/batterypowered instruments, pen digitizers, industrial controls, and data/signal acquisition.

Understanding SAR ADCs: their architecture and comparison with other ADCs - AN1080
Successive-approximation-register (SAR) analog-to-digital converters (ADCs) represent the majority of the ADC market for mediumto high-resolution ADCs. SAR ADCs provide up to 5Msps sampling rates with resolutions from 8 to 18 bits. 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 energy efficiency of ADCs has improved by orders of magnitude over the past two decades. Even though process scaling degrades the analog characteristics of transistors, by exploiting, scaling the energy efficiency of recently reported ADCs is approaching fundamental limits [1]. These improvements have been achieved through innovative circuit ideas and through the evolution of ADC architectu...

Digital wireless communication applications such as UWB and WPAN necessitate low-power high-speed ADCs to convert RF/IF signals into digital form for subsequent baseband processing. Considering latency and conversion speed, flash ADCs are often the most preferred option. Generally, flash ADCs suffer from high power consumption and large area overhead. On the contrary, SAR ADCs have low power di...
متن کاملIncrease Dynamic Range of Sar Adcs Using Oversampling
In some previous articles general overviews of Δ-Σ and SAR (successive approximation register) ADCs, the techniques of oversampling as it relates to signal-to-noise ratio (SNR) and effective number of bits (ENOB) have been covered. The oversampling technique is most often used with the Δ-Σ ADC, but it is also useful with the SAR ADC. In this article we will dive in a bit deeper to see how this ...
