Oversampling analog-to-digital and digital-to-analog converters are gaining more popularity in many signal processing applications. Delta-sigma modulators are used in practical applications of oversampling systems becau ...

A new approach to oversampled delta-sigma A/D converters ( AZ modulators ) is introduced, where a differential pseudo-Npath filter stage is used as a basic cell. In this band-pass application, the z to -zN transformation ...

This thesis describes the analysis and comparison of Folded Source-Coupled Logic (FSCL) with standard static CMOS, cascode voltage-switch logic and differential split-level logic gates. The advantages of FSCL are low s ...

This thesis describes the development of a flash analog-to-digital converter based on current-mode technique. The advantages of current -mode technique are higher speed, smaller chip area, and simple division of refere ...

With the increased demand for complex digital signal processing systems, real-time signal processing requires higher throughput systems. In the past, the throughput has been increased by increasing the clock rates, but ...

Multi-level decision feedback equalization (MDFE) is an effective technique to remove inter-symbol interference (ISI) from disk readback signals, which uses the simple architecture of decision feedback equalization. Para ...

The Discrete Cosine Transform is used in many image and video compression standards. Many methods have been developed for efficiently computing the Discrete Cosine Transform including flowgraph algorithms, distributed ...

Interference from other adjacent users in wireless applications is a major problem in direct-sequence code-division multiple-access (DS-CDMA). This is also known as the near-far problem where a strong signal from one u ...

In this dissertation, multi-rate array (MRA) architecture and its synthesis are proposed and developed. Using multi-coordinate systems (MCS), a unified theory for mapping algorithms from their original algorithmic spec ...

High-accuracy and high-speed CMOS track-and-hold (T/H) or sample-and-hold (S/H) circuits are an important part of the analog-to-digital interface. The switched-capacitor (SC) circuits usually contain one or more op-amps ...
