Book excerpt: "Historically, the microelectronics industry has scaled down CMOS transistor dimensions in order to increase operating speeds, decrease cost per transistor, and free up on-chip real estate for additional chip functions. There are numerous challenges involved with scaling transistors down to the near term 32 nm node, and beyond. These challenges include short gate lengths, very thin gate oxides, short channel effects, quantum effects, band-to-band tunneling from source to drain, Gate Induced Drain Leakage, Fowler-Nordheim tunneling, and increasing dopant concentrations. Field effect transistor circuits augmented with tunnel diodes lead to decreased circuit footprints, decreased device count, improved operating speeds, and lower power consumption without the need to solve current CMOS scaling challenges. Recently, N-on-P Si/SiGe resonant interband tunnel diodes (RITD) have been monolithically integrated with CMOS transistors. To further improve the benefits of RITD augmented circuits, P-on-N RITDS and all-Si RITDs were developed. Reported maximum peak-to-valley current ratios (PVCR), a key quantititaive parameter of TDs, of 1.32 and 3.02 were measured, respectively. Since integrated circuits operate at elevated temperatures, the I-V characteristsics of various TDs were measured at temperatures ranging from room temperature up to 200°C. Three figures of merit were extracted: (i) peak current density (Jp), *(ii) valley current density (Jv), and (iii) PVCR. Normalizing over their respective values at room temperature allowed for direct comparison between the various TD structures. This method allowed the author to determine that all devices show a similar Jp response. However, the Si/SiGe RITD structure was overall least sensitive to temperature variations. Furthermore, to design and optimize TD augmented circuits, a SPICE compatible model was developed. Past models have discontinuities, kinks in their slopes, difficut parameters to extract, unknown parameters, no closed form solutions, and/or poor fits to measured data. For this work a modified version of the S.M. Sze model with a superior match to experimental data, for Si based Esaki tunnel diodes (ETD) was developed. Using the developed model, several circuits were simulated, which were broken up into two groups. The first group of circuits is comprised of one TD and one of the following: (i) resistor, (ii) NMOS transistor, or (iii) TD. Finally, the behaviors learned from the simple circuits were used to simulate seeral TD augmented circuits such as (i) ADC comparator, (ii) TSRAM, (iii) and four basic logic gates."--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: "In this paper ECAP models for the tunnel diode are presented. Results showing the model, the current-voltage charateristics [sic] are discussed. Operation in typical circuits is presented. A summary of the current state of the art in modeling appears in Appendix I. Since ECAP is only structured to accept piecewise-linear models of these devices, that type of model is presented here. All of the models are developed to approximate the typical tunnel diode current-voltage characteristic"--Introduction, leaf 1.

This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
