Analog to digital converters on plastic foils
Proceedings of 2013 International Conference on IC Design & Technology (ICICDT), 2013Circuits based on transistors which are manufactured at near-to-ambient temperatures on plastic foils are suited for mechanically flexible and large-area applications. Examples include bendable displays, large-area sensor surfaces for man-machine interfaces, and sensors-augmented RFIDs embedded in packaging material for food monitoring.

A survey on nonlinear analog-to-digital converters
Integration, 2014This paper presents a survey on Nonlinear Analog-to-Digital converters (ADC). This class of converters is extremely relevant in applications where there is a need for non-uniform quantization characteristic, for example, some specific applications in the areas of light detection, hearing aid, nuclear physics, image acquisition, communication systems ...

Performance analysis of analog-to-digital converters
2012 20th Signal Processing and Communications Applications Conference (SIU), 2012Usage of digital receivers in today's radar and electronic warfare applications is becoming more common. Analog to digital converters (ADC) used in digital receivers play a significant role in the performance of these receivers. Therefore, it is very important to obtain performance analysis of possible ADC's under different conditions such as different

Traditionally in a receiver (as shown in Figure 2.1), upon mixing the input signal from RF to IF, subsequent demodulation can be performed in a couple of ways, depending on the kind of modulation used. In the case of DECT, since the input signal is phase modulated (GMSK for DE4CT), MSK demodulation for the digital encoded phase information should be ...

A novel flash analog-to-digital converter
2008 IEEE International Symposium on Circuits and Systems, 2008this paper a new ADC architecture of flash type is proposed. This proposed N-bit flash ADC replaces the (2N-1)-to- N encoder with two (2N/2 -1)-to-(N/2) encoders to accomplish the encoding of the least significant bits and the most significant bits respectively. A 6-bit ADC of this architecture is implemented.

A distortion model for pipeline Analog-to-Digital converters
2007 IEEE International Symposium on Circuits and Systems (ISCAS), 2007Pipeline analog-to-digital converters (ADC) are widely used to achieve high resolution and moderately high sampling frequency. In typical implementations, linearity is often limited by capacitor mismatch and finite amplifier gain. The impact of these non ideal effects on the overall linearity of the ADC has been addressed in this paper, obtaining a ...

Oversampling Analog-to-Digital Converter Design
21st International Conference on VLSI Design (VLSID 2008), 2008Summary form only given. Analog-to-digital converters (or sigma-delta) converters have now become routine aspects of high- performance signal processing, ranging from precision audio to RF transceivers. In this tutorial, we will present, in a systematic fashion, the basics and design aspects of delta-sigma data converters, along with a case study of a ...

Performance trends for analog to digital converters
IEEE Communications Magazine, 1999Analog-to-digital converters are key components of signal processing systems, and may even dictate system architectures due to their limitations on sampling rate and resolution. The state of the art for ADCs, including both experimental converters and commercially available parts, is reviewed.

Time-interleaved Analog-to-Digital Converters
2011This book describes the research carried out by our PhD student Simon Louwsma at the University of Twente, The Netherlands in the field of high-speed Analogto- Digital (AD) converters. AD converters are crucial circuits for modern systems where information is stored or processed in digital form.

As we have seen in Chapter 1, the registration of pulses corresponding to selected events is performed in digital devices. Therefore it is necessary to digitize the analog information carried by the pulse, i.e. to decide whether or not and where a given pulse should be registered.
