This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic range is an important metric that specifies the limits of input signal amplitude for the ideal operation of a given receiver. The low end of dynamic range is defined by the noise floor whereas the upper limit is determined by large-signal distortion. While dynamic range can be predicted in the temperature range where compact transistor models are valid, the lack of large-signal models at temperatures below -55 C prevents the prediction and optimization of dynamic range for applications that require cryogenic cooling. For decades, the main goal concerning the performance of these applications was lowering the noise floor of cryogenic receiver front-ends. For this, linear small-signal noise models have been extensively studied and used for designs of low-noise amplifiers. In this work, the existing small-signal noise modeling approach is extended to capture the weakly nonlinear properties of the transistors that are commonly used in cryogenic amplification. Indium phosphide high electron mobility transistors and silicon germanium heterojunction bipolar transistors are considered. The goal of this work is to identify the fundamental dynamic range limitations of these transistors such that the results are not device specific, but applicable to the corresponding device families. Identifying the fundamental limitations of dynamic range in a semiconductor device requires a broad understanding of physical properties of the transistors. For this, a theoretical analysis will be presented first as a function of temperature. The small-signal noise modeling will then be discussed using techniques that are well recognized in the literature. This will be followed by an explanation of the nonlinear modeling approach used in this work. This approach relies on the definition of Taylor series expansion coefficients of the dominant nonlinear mechanisms of the transistors. The modeling results will be interpreted with respect to the initially presented theoretical framework. Finally, the dynamic range performance will be studied as a function of source and load terminations. In addition to this systematic approach to understanding the physical limitations of dynamic range, model to measurement agreement of broadband cryogenic amplifiers will also be presented which will verify the accuracy of the modeling approach.

Available in PDF, EPUB and Kindle. Book excerpt: Most of the recent texts on compact modeling are limited to a particular class of semiconductor devices and do not provide comprehensive coverage of the field. Having a single comprehensive reference for the compact models of most commonly used semiconductor devices (both active and passive) represents a significant advantage for the reader. Indeed, several kinds of semiconductor devices are routinely encountered in a single IC design or in a single modeling support group. Compact Modeling includes mostly the material that after several years of IC design applications has been found both theoretically sound and practically significant. Assigning the individual chapters to the groups responsible for the definitive work on the subject assures the highest possible degree of expertise on each of the covered models.

This book was released on 2005-10-03 with total page 1080 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultimate handbook on microwave circuit design with CAD. Full of tips and insights from seasoned industry veterans, Microwave Circuit Design offers practical, proven advice on improving the design quality of microwave passive and active circuits-while cutting costs and time. Covering all levels of microwave circuit design from the elementary to the very advanced, the book systematically presents computer-aided methods for linear and nonlinear designs used in the design and manufacture of microwave amplifiers, oscillators, and mixers. Using the newest CAD tools, the book shows how to design transistor and diode circuits, and also details CAD's usefulness in microwave integrated circuit (MIC) and monolithic microwave integrated circuit (MMIC) technology. Applications of nonlinear SPICE programs, now available for microwave CAD, are described. State-of-the-art coverage includes microwave transistors (HEMTs, MODFETs, MESFETs, HBTs, and more), high-power amplifier design, oscillator design including feedback topologies, phase noise and examples, and more. The techniques presented are illustrated with several MMIC designs, including a wideband amplifier, a low-noise amplifier, and an MMIC mixer. This unique, one-stop handbook also features a major case study of an actual anticollision radar transceiver, which is compared in detail against CAD predictions; examples of actual circuit designs with photographs of completed circuits; and tables of design formulae.
