    The simulation of two electromagnetic compatibility (EMC) problems, namely crosstalk and field-to-wire coupling, using SPICE are described. These modeling techniques for simulation of EMC of multiconductor transmission lines allow calculation in the time domain, as well as the frequency domain. Nonlinearities, protective devices, and even complex circuitry can be included at both ends of the trans... View full abstract»

    Three categories of multiwatt, coherent laser designs are discussed. The designs are single-mode waveguides suitable for output powers in the order of 200 mW, single-mode operation of multimode lasers, which are suitable for operation between 0.5 and 1.0 W, and the monolithically integrated master-oscillator power amplifier (M-MOPA) designs that have demonstrated 4.5 W of spectrally coherent outpu...

    Past, present, and future developments in the field of light-emitting diode (LED) chips are discussed. It is argued that the performance of AlGaAs has enabled LEDs to penetrate markets requiring high flux and/or low power consumption and that AlInGaP technology, which yields high performance from red-orange to green, will accelerate the use of LEDs in new applications. Emerging blue devices and re... View full abstract»

    Verifying the design and simulation of 256 K SRAM relies on measurements of waveforms on internal nodes along a critical path. A technique for producing accurate measurements of these waveforms using electron-beam probing is described. Comparisons of measured and simulated waveforms at several points on a chip are presented. It is shown that the measured signals agree with the simulation in regard... View full abstract»

    Analog silicon-based neural hardware, which represents a large category among special-purpose analog and digital neurocomputers, and neural processing algorithms are reviewed. Artificial neural networks usually contain a large number of synaptic connections and many fewer processing neurons. The central problem in implementing artificial neural networks-making weights that are continuously adjusta... View full abstract»

    Factors such as minimum resolution overlay tolerances and maximum topography are key elements of IC fabrication. Circuit designers must understand the techniques lithographers use in manufacturing ICs. An overview of the resist work performed at SEMATECH, including resist characterization, process control, and modeling, and a look at future lithography trends are presented. Swing curve, exposure/f... View full abstract»
