Abstract:This paper presents design considerations for highresolution and high-linearity ADCs for biomedical imaging applications. The work discusses how to improve dynamic specifications such as Spurious Free Dynamic Range (SFDR) and Signal-to-Noise-and-Distortion Ratio (SNDR) in ultra-low power and high-resolution analog-to-digital converters (ADCs) including successive approximation register (SAR) for biomedical imaging application. The results show that with broad range of mismatch error, the SFDR is enhanced by ab… Show more
“…SAR ADC are researched and described for different applications such as Biomedical applications, wireless sensors, receivers, etc. [35,36,37,39,40,42] for its high speed performance. Another type of ADC: Flash ADC [38,41,43] is also proposed for many applications such as high-speed instrumentation, radar, wireless sensor network, DSO, digital TVs and so on.…”

The signal processing is advancing day by day as its needs and in wireline/wireless communication technology from 2G to 4G cellular communication technology with CMOS scaling process. In this context the high-performance ADCs, analog to digital converters have snatched the attention in the field of digital signal processing. The primary emphasis is on low power approaches to circuits, algorithms and architectures that apply to wireless systems. Different techniques are used for reducing power consumption by using low power supply, reduced threshold voltage, scaling of transistors, etc. In this paper, we have discussed the different types and different techniques used for analog to digital conversion of signals considering several parameters.
