Book excerpt: An on-wafer microwave characterization system has been developed that allows for both 'frequency domain' swept frequency fixed power small signal s-parameter measurements and 'time domain' swept power fixed frequency large signal power measurements of transistors from 0.5 GHz to 40 GHz. The 'time domain' measurements are fully vector corrected to allow for the determination of both magnitudes and phases of the harmonise generated in the nonlinear regime. Such measurement capability allows for the measurement of the large signal voltage and currents waveforms present at the transistor terminations under large signal microwave excitation. The availability of these waveforms not only provides detailed insight into the operation of the transistor under large signal conditions, but is also revolutionizing the development, optimization and extraction of non-linear models and circuits design techniques. The charcterization techniques are illustrated through measurements on 025\im gate transistors fabricated using the H40 process at GMMT having a 4x60 m gate width.

This book was released on 2019-12-31 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: All model parameters are fundamentally coupled together, so that directly measured individual parameters, although widely used and accepted, may initially only serve as good estimates. This comprehensive resource presents all aspects concerning the modeling of semiconductor field-effect device parameters based on gallium-arsenide (GaAs) and gallium nitride (GaN) technology. Metal-semiconductor field-effect transistors (MESFETs), high electron mobility transistors (HEMTs) and heterojunction bipolar transistors (HBTs), their structures and functions, and existing transistor models are also classified. The Shockley model is presented in order to give insight into semiconductor field-effect transistor (FET) device physics and explain the relationship between geometric and material parameters and device performance. Extraction of trapping and thermal time constants is discussed. A special section is devoted to standard nonlinear FET models applied to large-signal measurements, including static-/pulsed-DC and single-/two-tone stimulation. High power measurement setups for signal waveform measurement, wideband source-/load-pull measurement (including envelope source-/load pull) are also included, along with high-power intermodulation distortion (IMD) measurement setup (including envelope load-pull). Written by a world-renowned expert in the field, this book is the first to cover of all aspects of semiconductor FET device modeling in a single volume.

Download or read book RF and Microwave Circuits Measurements and Modeling written by Mike Golio and published by CRC Press. This book was released on 2018-10-08 with total page 772 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highlighting the challenges RF and microwave circuit designers face in their day-to-day tasks, RF and Microwave Circuits, Measurements, and Modeling explores RF and microwave circuit designs in terms of performance and critical design specifications. The book discusses transmitters and receivers first in terms of functional circuit block and then examines each block individually. Separate articles consider fundamental amplifier issues, low noise amplifiers, power amplifiers for handset applications and high power, power amplifiers. Additional chapters cover other circuit functions including oscillators, mixers, modulators, phase locked loops, filters and multiplexers. New chapters discuss high-power PAs, bit error rate testing, and nonlinear modeling of heterojunction bipolar transistors, while other chapters feature new and updated material that reflects recent progress in such areas as high-volume testing, transmitters and receivers, and CAD tools. The unique behavior and requirements associated with RF and microwave systems establishes a need for unique and complex models and simulation tools. The required toolset for a microwave circuit designer includes unique device models, both 2D and 3D electromagnetic simulators, as well as frequency domain based small signal and large signal circuit and system simulators. This unique suite of tools requires a design procedure that is also distinctive. This book examines not only the distinct design tools of the microwave circuit designer, but also the design procedures that must be followed to use them effectively.

Available in PDF, EPUB and Kindle. Book excerpt: Design techniques for nonlinear microwave circuits are much less developed than for linear microwave circuits. Until now there has been no up-to-date text available in this area. Current titles in this field are considered outdated and tend to focus on analysis, failing to adequately address design and measurement aspects. Giannini and Leuzzi provide the theoretical background to non-linear microwave circuits before going on to discuss the practical design and measurement of non-linear circuits and components. Non-linear Microwave Circuit Design reviews all of the established analysis and characterisation techniques available and provides detailed coverage of key modelling methods. Practical examples are used throughout the text to emphasise the design and application focus of the book.

Download or read book Modular Nonlinear Characterization System and Large signal Behavioral Modelling of Unmatched Transistors for Streamlined Power Amplifier Design written by Dylan Bespalko and published by . This book was released on 2016 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis provides a comprehensive approach to the characterization and modelling of large-signal nonlinear RF/microwave devices, circuits and systems. This research is moti- vated by the increased linearity and power-efficiency requirements of modern power ampli- fier technology for wireless communications. For instance, maximizing the power amplifier's efficiency can only be achieved by operating RF transistors under strong nonlinear condi- tions, however this is contradictory to maximizing PA linearity. Simultaneously designing for efficiency and linearity is a challenging trade-off in today's fragmented design process, therefore the advancement of computer-aided design (CAD) tools is essential for achieving an optimal solution. The successful and effective CAD tool based PA design relies on the availability of accurate nonlinear models to mimic the electro-thermal behaviour of RF transistors. The accuracy of these models depends on three factors: 1. The formulation of the model. 2. The model extraction procedure. 3. The accuracy of the measurement data. While prior work focuses separately on the improved model formulations or improving characterization accuracy, this thesis provides a comprehensive analysis of all three factors. This thesis proposes a modular large-signal RF device characterization system, and a non- linear behavioral model capable of handling strongly nonlinear unmatched RF transistors, each necessary to streamline the design process and achieve a first-pass PA design. iii As a first step, a large-signal characterization system has been developed to measure the multi-harmonic frequency response of RF transistors and has the ability to i) Perform high-power measurements, ii) Characterize unmatched transistors, iii) Operate the DUT under any possible operating condition, iv) Synthesize any multi-harmonic stimulus, and v) Reconstruct the time-domain I/V waveforms at the ports of the DUT. The proposed characterization system eliminates fragmentation between measurement and simulation environments by providing seamless integration with Harmonic Balance simulations. This provides a common framework that integrates all steps of the PA design process from device-level characterization, to circuit-level measurement and validation. This system is implemented using modular instruments consisting of mixer-based receivers, arbitrary waveform generators, impedance tuners, and a multi-harmonic phase-coherent reference source. It also integrates sequential calibration routines to provide receiver, port match, and source-power corrections to the DUT measurement plane and measurement routines for automated data collection. The second part of the thesis researches black-box frequency-domain behavioral mod- els that can approximate strongly nonlinear, unmatched devices. Our investigation yielded two complimentary solutions to ensure the targeted modelling accuracy. First, improving the accuracy of a first-order expansion-based Poly-Harmonic Distortion (PHD) model by 5dB, in terms of Normalized Mean-Squared Error (NMSE), by minimizing multi-harmonic reflections that artificially increase the order of the nonlinear system. While this addresses the fictitious need for higher-order models due to the deficiencies in the model extraction procedure, strongly nonlinear devices will require high-order models to achieve the targeted accuracy over a larger measurement distribution. Hence, a variable order Multi-Harmonic Volterra (MHV) model is proposed to extend the PHD model formulation to strong non- linear devices. This model is extracted by utilizing the proposed characterization system to extract higher-order multi-variate model coefficients not included in the PHD model. The resulting model improves DC drain current prediction by 5dB and improves funda- mental output-power prediction by 2dB. The MHV model improves the vector power-gain prediction by 3.4dB in realistic PA design applications, thereby providing better emulation of linearization techniques within a simulation environment. Finally, a concurrent dual-band PA design is studied as an example of how the pro- iv posed nonlinear characterization system and behavioural modelling approach can be used to enable complex PA designs. First, a 10W Class-AB PA is designed using dual-band matching-network theory, however it is difficult to implement because the design technique does not control the matching fractional bandwidth as a design parameter. Therefore, an alternative Class-J 45W dual-band PA was designed using a low-impedance matching network, combined with a trans-impedance dual-band filter. Although the dual-band PA can achieve comparable performance to an equivalent single-band PA at each separate fre- quency, further development of characterization, modeling, and circuit design techniques is needed to achieve high-efficiency during concurrent operation.
