Advancements in the sophistication and complexity of modern electronic systems are creating a need for highly integrated systems with ever higher operational frequencies. The economical demands of these systems dictate that they be implemented using low cost fabrication technologies, such as digital CMOS. One of the major challenges facing circuit...
The ability to integrate designs from board level, multi-chip modules to single process solutions is highly attractive in today's PC multimedia industry. Saving board area and chip count will decrease the production cost of personal computing hardware and increase profitability. The ability to integrate analog circuit capability and it's reference...
Decision feedback equalization (DFE) is a sampled-data technique used for data recovery in digital communications channels. Multi-level decision feedback equalization (MDFE) has been developed for channels using the 2/3(1,7) RLL code.
The optimum detector for a digital communication channel affected by ISI and noise consists of a matched filter, followed...
In recent years, there has been an extensive effort to develop low-cost implementations
of radio frequency integrated circuits for consumer applications. This thesis is a
research effort in the design and implementation of integrated RF CMOS Power Amplifiers
(PAs). A significant challenge in the implementation of RF CMOS ICs is...
With increasing interest in current-mode analogue processing due to its high
performance properties such as speed, bandwidth and accuracy compared to voltage-mode
processing, new current-mode alternatives to various conventional circuit designs are
appearing. In this report, a novel circuit design to construct a fully-differential current-mode
operational amplifier ( OP-AMP )...
In this dissertation, two important current mode circuit design subjects have
been explored. In the first part, the switched-current circuit technique has been
investigated. The fundamental performance and limitations of this technique are
explored. One of the major limitations, the signal distortion caused by clock
feedthrough has been substantially reduced...
A method and apparatus are presented for generating suppressed carrier digital clock signals. These clock signals have the advantage of being broad band in nature and thus exhibiting lower power spectral density. Structures or systems utilizing such clock signals would be less likely to create electromagnetic noise of sufficient intensity...
An experimental investigation of factors effecting
scheduling a system of parallel, non-identical processors
using a series of experimental designs was carried out.
System variables included were processor capacities
relationships, sequencing and assignment rules, job size, and
product demand distributions. The effect of the variables was
measured by comparing mean flow...
