The paper presents a mathematically grounded approach to the analysis and optimisation of multi-pass analogue-to-digital converters (MADCs) with the algorithmic forming the estimates of converted samples. The approach enables a comprehensive analysis of the

Comparison of Apparent Diffusion Coefficient ( ADC ) with Histologic Cellularity in Breast Tumors [J]
free download

Lucas-Quesadas and our previous studies [ 2] showed that the ADCs of benign and malignant breast lesions were different and measuring the ADCs of focal breast masses was useful for characterizing the masses. But the overlap in ADC between benign and malignant

ADC histogram test using small amplitude input waves
free download

The experimental investigation on a histogram test for analog-to-digital converters (ADCs) using as stimulus signals small-amplitude triangular waves superimposed to variable DC levels is presented. The test allows inexpensive triangular generators to be used and a

ADC noise figure An often misunderstood and misinterpreted specification
free download

W Kester- Analog Devices mouser.com.gt Noise figure (NF) is a popular specification among RF system designers. It is used to characterize the noise of RF amplifiers, mixers, etc., and widely used as a tool in radio receiver design. Many excellent textbooks on communications and receiver design treat

Design of low power sigma delta ADC

ABSTRACT A Low power discrete time sigma delta ADC consisting of a second order sigma delta modulator and third order Cascaded Integrated Comb (CIC) filter is proposed. The second order modulator is designed to work at a signal band of 20K Hz at an oversampling

Capacitive Touch Using Only an ADC ( CVD )
free download

This application note describes a new hardware sensing method called Capacitive Voltage Divider (CVD) which uses no external components. It requires only the ADC to perform capacitive touch sensing. The principle is simple, and can be applied to nearly any

Uncertainty in the ADC transition voltages determined with the histogram method

A sample hold circuit, a comparator and a decision flip-flop are implemented in 90 nm standard CMOS technology. The input switch of the sample hold circuit provides a bandwidth in excess of 30 GHz at a sampling rate of 10 Gs/s. The limiting amplifier based

SAR ADC architecture with digital error correction
free download

This paper describes a high-performance successive approximation (SAR) ADC using three comparators operating in parallel, instead of just one as in conventional ADCs. This comparator redundancy enables higher resolution, potentially faster operation, higher

ADC based measurements: A common basis for the uncertainty estimation
free download

In the last years, many Authors have dealt with the uncertainty evaluation of the measurement performed by using an analog-to-digital converter, proposing different approaches to analyze the uncertainty propagation. However, in these studies, in order to

Achieving higher ADC resolution using oversampling
free download

An Analog-to-Digital Converter ( ADC ) is an active interface between the analog and digital signal chains in an embedded system. An ADC converts analog signals into digital signals in electronic systems. The key feature of an ADC is the accuracy (resolution) it offers. The

A new approach to optimization of adaptive ADC with multi-pass residual compensation
free download

The aim of the paper is to present a new approach, based on the conception of adaptive fitted observation [1-5], applied to analysis, synthesis and optimization of the structure and parameters of multi-pass compensatory analog-to-digital converters ( ADC ) with optimally The trends of technological market have been changing, giving special relevance to the interaction between consumer and product. Displays are probably the best demonstration of this trend, being deeply integrated in our daily life in televisions (TVs), smartphones

Measurement of ADC integral nonlinearity via DFT

This paper presents design and implementation of a 9-bit folding and interpolation ADC using 0.35 µm CMOS C35B4 model under AMS-HIT Kit Library. The complete system consists of two main blocks. One of them is 4-bit flash ADC , which is based on the so-called

trial: Phase II study of gefitinib administered as first-line treatment in non-resectable adenocarcinoma with bronchioloalveolar carcinoma features ( ADC -BAC)
free download

Background: ADC -BACs are distinguished from other ADCs by epidemiological, clinical and CT scan presentations as well as molecular biology, leading to some responses to EGF-TKI. We therefore conducted a prospective, multicentric, phase II trial to evaluate gefitinib (250
