Book excerpt: Integrated Inductors are a fundamental element in voltage-controlled oscillators, low noise amplifiers and LC filters. In this work a model based in lumped elements is presented for the characterization of integrated inductors. With this model, it is possible to design integrated inductors with different topologies, for a wide range of frequencies, by granting the evaluation of important design parameters such as inductance, quality factor and self-resonance frequency. The model used is based on analytical equations and this equations will be explained in detail. In order to validate the model, some comparisons are made against electromagnetic (EM) simulations in two different technologies, a 0.13 um and 0.35 um CMOS technology. Also, a statistic analysis is presented in order to validate the model over a wide range of geometric variables and the validation is done against electromagnetic simulations for a 0.35 um CMOS technology. Variable width integrated inductors are also studied as a way of increasing the quality factor of inductors. In the end, the model is integrated into two different optimizations processes. Both single and multi-objective optimization.

This book was released on 2005-12-15 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: The modern wireless communication industry has put great demands on circuit designers for smaller, cheaper transceivers in the gigahertz frequency range. One tool which has assisted designers in satisfying these requirements is the use of on-chip inductiveelements (inductors and transformers) in silicon (Si) radio-frequency (RF) integrated circuits (ICs). These elements allow greatly improved levels of performance in Si monolithic low-noise amplifiers, power amplifiers, up-conversion and down-conversion mixers and local oscillators. Inductors can be used to improve the intermodulation distortion performance and noise figure of small-signal amplifiers and mixers. In addition, the gain of amplifier stages can be enhanced and the realization of low-cost on-chip local oscillators with good phase noise characteristics is made feasible. In order to reap these benefits, it is essential that the IC designer be able to predict and optimize the characteristics of on-chip inductiveelements. Accurate knowledge of inductance values, quality factor (Q) and the influence of ad- cent elements (on-chip proximity effects) and substrate losses is essential. In this book the analysis, modeling and application of on-chip inductive elements is considered. Using analyses based on Maxwells equations, an accurate and efficient technique is developed to model these elements over a wide frequency range. Energy loss to the conductive substrate is modeled through several mechanisms, including electrically induced displacement and conductive c- rents and by magnetically induced eddy currents. These techniques have been compiled in a user-friendly software tool ASITIC (Analysis and Simulation of Inductors and Transformers for Integrated Circuits).

Download or read book Inductors in High performance Silicon Radio Frequency Integrated Circuits written by Richard D. Lutz and published by . This book was released on 2005 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spiral inductors are a key component of mixed-signal and analog integrated circuits (IC's). Such circuits are often fabricated using silicon-based technology, owing to the inherent low-cost and high volume production aspects. However, semiconducting substrate materials such as silicon can have adverse effects on spiral inductor performance due to the lossy nature of the material. Since the operating requirements of many high performance IC's demand reactive components that have high Quality Factor's (Q's), and are thus low loss devices, the need for accurate modeling of such structures over lossy substrate media is key to successful circuit design. The Q's of commonly available off-chip inductors are in the range of 50- 100 for frequencies ranging up to a few gigahertz. Since off-chip inductors must be connected through package pins, solder bumps, etc., which all contribute additional loss and thus lower the apparent Q of an external device, the typical on-chip Q requirement for a given RFIC design is generally lower than that for an off-chip spiral solution. However, a spiral inductor that was designed and fabricated originally in a low loss technology such as thin-film alumina may have substantially worse performance in regard to Q if it is used in a silicon-based technology, owing to the conductive substrate. For this reason, it is imperative that semiconducting substrate effects be accurately accounted for by any modeling effort for monolithic spirals in RFICs. This thesis presents a complete modeling solution for both single and multi-level spiral inductors over lossy silicon substrates, along with design considerations and methods for mitigation of the undesirable performance effects of semiconducting substrates. The modeling solution is based on Spectral Domain Approach (SDA) solutions for frequency dependent complex capacitive (i.e. both capacitance and conductance) parasitic elements combined with a quasi-magnetostatic field solution for calculation of the frequency dependent complex inductive (i.e. both inductance and resistance) terms. The effects of geometry and process variations are considered as well as the incorporation of Patterned Ground Shields (PGS) for the purpose of Q enhancement. Proposals for future extensions of this work are discussed in the concluding chapter.

Download or read book Integrated Inductors written by Mandar Dilip Kavimandan and published by . This book was released on 2008 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated inductors, also called spiral inductors, on-chip inductors, or planarinductors, are inseparable part in radio frequency integrated circuits (RFICs). Increasing growth in RFICs from the past few decades has forced study of these components in greater detail. Apart from IC inductors, there are several components mounted on a chip - namely capacitors, resistors, MOSFETs, diodes etc. It is extremely important to understand the electrical and magnetic behavior of all these components. Electrical behavior of these components is easy to understand. However, the real challenge lies in realizing and predicting the magnetic behavior of components, namely, inductors and capacitors. Capacitors have their own physical model developed for accurate modeling, but for inductors there are many factors to be considered. As the frequencies in RFICs are in the GHz range, factors such as self resonant frequency (SRF), quality factor (Q), self and mutual inductance are critical to design due to the very small size of inductor. Past research in this field has made it possible to predict magnetic behavior accurately by theoretical methods and/or electromagnetic simulators. Apart from these simulators, various equations have been derived for accurate calculation of inductance related to several geometries. Lumped physical models developed in the past help to model parasitic elements most accurately. This thesis concentrates on a brief study of integrated inductors, their construction and modeling. Different electromagnetic simulators available in the market are reviewed. A MATLAB based spiral and pi network calculators have been developed. Spiral calculators help to compare different equations while a pi calculator solves for parasitic components depending on substrate material, dielectric layer thickness, and metal oxide thickness. The main aim of this research was to design a theoretical design procedure for designing inductor internal dimensions. It has been described briefly with the design example. The proposed method makes it easy to design internal dimension such as the inner diameter (d), width (w), spacing (s), height (h), and number of turns (N). The results obtained are closer to the desired ones.

Download or read book CMOS RF Modeling Characterization and Applications written by M. Jamal Deen and published by World Scientific. This book was released on 2002 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: CMOS technology has now reached a state of evolution, in terms of both frequency and noise, where it is becoming a serious contender for radio frequency (RF) applications in the GHz range. Cutoff frequencies of about 50 GHz have been reported for 0.18 æm CMOS technology, and are expected to reach about 100 GHz when the feature size shrinks to 100 nm within a few years. This translates into CMOS circuit operating frequencies well into the GHz range, which covers the frequency range of many of today's popular wireless products, such as cell phones, GPS (Global Positioning System) and Bluetooth. Of course, the great interest in RF CMOS comes from the obvious advantages of CMOS technology in terms of production cost, high-level integration, and the ability to combine digital, analog and RF circuits on the same chip. This book discusses many of the challenges facing the CMOS RF circuit designer in terms of device modeling and characterization, which are crucial issues in circuit simulation and design.
