Design of Hybrid Filter Banks for Analog/Digital Conversion

by Scott R. Velazquez, Truong Q. Nguyen, Senior Member, Steven R. Broadstone - IEEE Trans. on Signal Processing , 1998
"... This paper presents design algorithms for hybrid filter banks (HFB's) for high-speed, high-resolution conversion between analog and digital signals. The HFB is an unconventional class of filter bank that employs both analog and digital filters. When used in conjunction with an array of slower s ..."

Biologically Motivated Analog-Digital Conversion Technique

by Mark Buck, Daaron Spears, Faculty Advisors, Brian Gollsneider, Dr. J. Scot Ransbottom , 2005
"... Biological neurons acting alone are inefficient and noisy, yet are able to work together to produce a large dynamic response over a wide frequency range. This behavior suggests using interconnected low-level electronics to represent the conversion of analog signals to digital temporal patterns for s ..."

Tx Leakage impact on analog-digital conversion in zero-IF receivers

by Andreas Frotzscher, Gerhard Fettweis - in Proc. IEEE Veh. Technol. Conf. (VTC 2009 Fall , 2009
"... Abstract—Transmitter Leakage has a significant impact on the system performance in mobile devices using zero-IF receivers and thus requires a suitable compensation. In contrast to analog approaches, digital Tx Leakage compensation approaches can easily be reconfigured and therefore are highly attrac ..."

Secure spread spectrum watermarking for multimedia

by Ingemar J. Cox, Joe Kilian, F. Thomson Leighton, Talal Shamoon - IEEE TRANSACTIONS ON IMAGE PROCESSING , 1997
"... This paper presents a secure (tamper-resistant) algorithm for watermarking images, and a methodology for digital watermarking that may be generalized to audio, video, and multimedia data. We advocate that a watermark should be constructed as an independent and identically distributed (i.i.d.) Gauss ..."

Quantization

by Robert M. Gray, David L. Neuhoff - IEEE TRANS. INFORM. THEORY , 1998
"... The history of the theory and practice of quantization dates to 1948, although similar ideas had appeared in the literature as long ago as 1898. The fundamental role of quantization in modulation and analog-to-digital conversion was first recognized during the early development of pulsecode modula ..."

1Analog-to-Digital and Digital-to-Analog Conversion with Memristive Devices

by Yuriy V. Pershin, Edward Sazonov, Massimiliano Di Ventra
"... Abstract—We suggest a novel methodology to obtain a dig-ital representation of analog signals and to perform its back-conversion using memristive devices. In the proposed converters, the same memristive systems are used for two purposes: as ele-ments performing conversion and elements storing the co ..."

Bandwidth mismatch and its correction in time-interleaved analog-to-digital converters

by Tsung-heng Tsai, Paul J. Hurst, Stephen H. Lewis - IEEE Trans. Circuits Syst. II , 2006
"... 3/27/2006>REPLACE WITH YOUR PAPER IDENTIFICATION NUMBER (DOUBLE-CLICK HERE TO EDIT)< Abstract—The sample-and-hold amplifier (SHA) in each channel of a time-interleaved analog-to-digital converter system has finite bandwidth, and these bandwidths may be mismatched. This paper analyzes the effec ..."

MODELING MEMORY ERRORS IN PIPELINED ANALOG-TO-DIGITAL CONVERTERS

by unknown authors
"... Switched-capacitor implementations of pipelined ADCs contain several sources of memory errors, including capacitor dielectric absorption/relaxation, incomplete stage reset at high clock rates, and parasitic capacitance effects when op amps are shared between subsequent pipeline stages. This paper de ..."
