A 1-m W, 14-bit [sigma] [delta] A/D converter with 10-KHz conversion rate

Creator:: Gupta, Shivani
Resource Type:: Masters Thesis

A graphic user interface for monophonic music analysis

Creator:: Matos G., Soraya J.
Abstract:: A Graphic User Interface is developed to determine the existence of a particular sequence of piano notes within a monophonic sound waveform. Such waveforms are recorded within the Graphic User Interface and then passed to the monophonic analysis engine. The first phase of analysis segments the PCM sound data to...

Analog integrated circuit design using GaAs C-HFETs

Creator:: Gupta, Rakhee
Abstract:: Present day data processing technology requires very high speed signal processing and data conversion rates. One such application which requires high speed is switched capacitor circuits used in Sigma-Delta modulators. A major active component of switched capacitor circuits is the monolithic operational amplifier(opamp). Because of the relatively poor speed performance...

Delta-sigma modulators employing continuous-time circuits and mismatch-shaped DACs

Creator:: Zhang, Bo
Abstract:: Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital and digital-to-analog converters. These oversampled data converters have several advantages over conventional Nyquist-rate converters, including an insensitivity to many analog component imperfections, a simpler antialiasing filter and reduced accuracy requirements in the sample and hold. Though the initial...

Resource Type:: Masters Thesis

High speed digital FIR filter design

Creator:: Zhou, Bo
Abstract:: The objective of this thesis is to design a high speed digital FIR filter. The inputs of the system come from a Delta-Sigma modulator. This FIR filter takes 1024 inputs, multiplies them with their coefficients and adds the results. The main design task is to take the input data, which...

Resource Type:: Dissertation

Rapid hardware implementations of classical modular multiplication

Creator:: Johnson, Scott Andrew
Abstract:: Modular multiplication is a mathematical operation fundamental to the RSA cryptosystern, a public-key cryptosystem with many applications in privacy, security, and authenticity. However, cryptosecurity requires that the numbers involved be extremely large, typically ranging from 512-1024 bits in length. Calculations on numbers of this magnitude are cumbersome and lengthy; this...

Scheduling system of affine recurrence equations by means of piecewise affine timing functions

Creator:: Mui, Lap K.
Abstract:: Many systematic methods exist for mapping algorithms to processor arrays. The algorithm is usually specified as a set of recurrence equations, and the processor arrays are synthesized by finding timing and allocation functions which transform index points in the recurrences into points in a space-time domain. The problem of scheduling...
