    The design and optimization of ESD protection circuits is greatly enhanced by the ability to perform circuit-level simulations of the protection circuits and the I/O buffers. Most available simulators do not cover the high current region of the circuit operation, but still enable an approximate analysis to be made of the behaviour under ESD conditions. In this article, a description of the behaviour of the MOS device in the high current regime is presented together with the model equations governing that behaviour. The equations have been implemented into a SPICE circuit simulator, and the experimental and simulation results are given. A simple parameter extraction methodology is presented that uses the terminal currents from a single MOS DC I-V curve to obtain all the MOS and bipolar parameters required for the model View full abstract»

    In this article we discuss the flow of design for neural network hardware and go deeper into the design constraints and implementation possibilities. The performance measures and problems of different measurements are also discussed. It is noted that performance is one comparison criteria, but there are also many others, some of which are also discussed. In order to anchor the discussion to real life, the article includes a case study of our TUTNC neurocomputer. In addition, examples of commercial neural computing systems and their world wide web pages are given View full abstract»

    Distance learning entails a major commitment in time and money for organizations, trainers, and administrators. Planning to estimate the most appropriate time to go on-line must be done now. Sooner or later, distance learning will affect us all. Opportunities for technical communicators lie in becoming proficient in the platform skills and strategies for instructional design, so this potential “danger” can be turned into the opportunity it truly is View full abstract»

    Expectations are that by the end of the first quarter of the next century, accessibility to the telephone will be universal. Virtually, the entire population will be free of the telephone cord and the home or office connection. To meet these expectations, more effective utilization of available cellular bandwidth is needed. As demand for higher performance and increased bandwidth grows, the need for compound semiconductors, which are already used in cordless telephone sets and in some networks, will also grow. This article presents an overview of wireless systems, and methods used for signal modulation coding and decoding, flexible satellites, and handset and hardware requirements will be discussed. Laced with the hardware discussion will be the uses of compound semiconductor devices and circuits View full abstract»

    We verified that contemporary microprocessors follow a form of Rent's rule as applicable for functionally partitioned circuits and, hence, present far fewer pins than that predicted by the SIA. We have also suggested a correction scheme for application of Rent's rule to recent VLSI circuits that would yield the correct (slower) rate of increase in pin requirements of these circuits. Finally, the reasons for using such a large number of power and ground pins in current VLSI circuits have been elaborated in detail View full abstract»
