Title Proper : A NOVEL COMPRESSING ANALOG-TO-DIGITAL CONVERTER
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Analog-to-digital converters form the backbone of many real world systems.A compression and expansion (companding) capability is a useful tool to increase thesignal-to-noise ratio of many of these applications. Frequently, power-signal systemsutilize analog compression to simplify signal processing. A novel compressing highspeedconverter is presented in this thesis. The converter described here has a naturalcompressing transfer function of f(x)=1-1/x. The converter is a variation on Flashconversion, so it is high speed, with a sampling frequency of 80MHz. A four bitimplementation of this converter was manufactured on a 0.5m CMOS process withan area of 0.018mm2. The power consumed was 50mW on a first pass design. Thecompressing converter will to scale with process improvements. The converterdesensitizes the linear region to reference mismatch, and arbitrary compressingtransfer functions can be obtained..............-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
