As the number of transistors on a single integrated circuit approach a billion, the problems of clock distribution, power consumption, multiple clock domains, meeting timing requirements, and reuse of subsystem designs grow ever more difficult. Coordinating a billion transistors with the present design methodologies will require hundreds of years of engineering time. A new design methodology is...

An integrated circuit has been designed to investigate the quantization of energy levels in an RF SQUID. The experiment is very similar to the rapid-sweep technique of Silvestrini et al., except that it is accomplished by using superconducting digital electronic circuitry as the experimental apparatus. This allows the system being studied to be very well isolated from its environment. ( 2000 El...

This paper presents the current tendency in automotive industry, analyses the influence into the Integrated Circuit (IC) design, and proposing project and process transferable solutions for overcoming some of the common problems.

Guillotine partitions play an important role in many research areas and application domains, e.g., computational geometry, computer graphics, integrated circuit layout, and solid modeling, to mention just a few. In this paper we present an exact summation formula for the number of structurally-different guillotine partitions in d dimensions by n hyperplanes, and then show that it is Θ (( 2d− 1 ...

ii ACKNOWLEDGEMENTS It has been a great privilege to be a graduate student in the Electrical and Computer Engineering department at the Texas Tech University and work closely with my advisor Prof. Dr. Kwong S. Chao. His keen insight into system and integrated circuit design is the key factor in the success of this research. I would also like to thank Prof. Dr. Sunanda Mitra, for her willingness...

SIGMA Adequate and understandable MOSFET models are presently a must for the design of integrated circuits. Most of the existing MOSFET models, however, are too complex andor do not comply with basic principles of physics. We propose here the use of ACM model, a very simple transistor model, together with a set of easily implemented experiments to determine the ACM parameters for the training o...

A two-port electroacoustic analogous circuit model for finite-length acoustic horns belonging to Salmon’s family of horns is described. The circuit is useful for simulation of horn-loaded electroacoustic systems with electric circuit simulator software such as SPICE ~simulation program with integrated circuit emphasis!. An implementation of the circuit model for use with the PSpice simulator so...

This paper covers the evaluation and fine-tuning of different values of genetic operator’s parameters in the process of optimizing the designs of the integrated circuits. We investigated the interdependence of various values of these parameters in the use over the set of test-bench circuits, as well as their influence on the quality of the final solution and the convergence speed. Due to the in...
