This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with the analysis and design of Low phase Noise Local-Oscillator(LO) sources suitable for backhauling applications on the frequencies 30-38GHz. The LO is intended to be used in a low-IF architecture for low order modulations (2-3 bits/symbol). This work was developed in collaboration with NXP Semiconductorsat CAEN, France, within the project RF2THz of the European program CATRENE.The original contributions in this work include a rigorous study of the 1/f2 phasenoise characteristics of the VCO (bipolar cross-coupled pair Voltage-Controlled-Oscillator) with the oscillating frequency. Key factors in the design of VCOs such as tuning range and the tank load given by the cross-coupled pair are considered in the analysis. The study reveals that as the frequency scales, the VCO passes through two different zones, named the QL-limited and the QC-limited region, that results from the dependence of the resonator quality factor on its inductive part (for low oscillating frequencies) and its capacitive part (for high oscillating frequencies). Moreover, the impact of the tuning range on the 1/f2 phase noise evolution was captured by using a classical circuit based on an AC-coupled varactor and a MiM capacitor. Simple and accurate equations were derived for the circuit parameters in order to achieve a desired central frequency with the required capacitance variation. For this circuit, it is demonstrated (and verified through circuit simulations) that the lowest quality factor scenario can be associated to the time-constant of a lossy capacitor. The latter allows to estimate easily the minimum quality factor of the capacitive part of the VCO LC tank, for a given tuning range, as a function of the oscillating frequency. In a similar way, and based on a small signal analysis, the time-constant of the output capacitance of the bipolar cross-coupled pair was derived. Interesting, this time constant shows a constant behavior over a wide frequency range, thereby allowing to estimate easily its quality factor. This study set the bases for an analytical framework that enables the evaluation of the 1/f2 phase noise performances of local oscillator sources working either on fundamental,super-harmonic or sub-harmonic mode. The superiority in terms of 1/f2 phase noise of local oscillators based on sub-harmonic oscillators is thus demonstrated and simple equations are derived to determine the maximum performance and the conditions on which this can be achieved. Finally, a signal generation system intended for a low-IF point-to-point fixed radio system in the Ka-Band band is thus designed and verified through prototype measurements.The system is composed by a sub-harmonic VCO followed by an injectionlocked frequency tripler (ILFT) and it is designed in a 0.25m BiCMOS SiGe:C technology. The ILFT implements a cascode current-biased common emitter configuration that exploits the second harmonic of the VCO to enhance the efficiency in the generation of the injecting signal responsible for the ILFT locking. At 30.8GHz, the system achieves a phase noise of -112dBc/Hz at 1MHz offset. The total current consumption is 38mA for a supply voltage of 2.5V. A second prototype is designed for a multiband LO generation, providing thus three RF outputs at 18GHz, 34GHz and 68GHz. With a measured tuning range of 10% for each RF output, the measured phase noise at 1MHz is -113dBc/Hz, -107dBc/Hz and -100dBc/Hz respectively.

Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we present a 10/30GHz MMIC Tripler, an X-band VCO and a frequency divider using a 0.35 æm, 60 GHz-fMAX MMIC BiCMOS SiGe technology. The Tripler exhibits a conversion gain of -5 dB and a low additive phase noise of - 43dBc/Hz at a frequency offset of 100kHz is anticipated. In order to drive this Tripler, the design of a MMIC X-band VCO and its measured performance (0.8GHz tuning range, -5 dBm output power and - 7dBc/Hz phase noise @ 100kHz of carrier) is also reported. This X band VCO can also drive a frequency divider, developed in the same technology. The assembling of these circuits allows the design of a 2 GHz frequency synthesizer. Measurements have shown a phase noise of -99dBc/ Hz at a frequency offset of 100kHz. Therefore, this paper demonstrates the great capabilities of BiCMOS SiGe MMIC technology about frequency synthesis ranging from 2GHz to 30GHz.

Download or read book Op Amps for Everyone written by Ron Mancini and published by Newnes. This book was released on 2003 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: The operational amplifier ("op amp") is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp. This book is Texas Instruments' complete professional-level tutorial and reference to operational amplifier theory and applications. Among the topics covered are basic op amp physics (including reviews of current and voltage division, Thevenin's theorem, and transistor models), idealized op amp operation and configuration, feedback theory and methods, single and dual supply operation, understanding op amp parameters, minimizing noise in op amp circuits, and practical applications such as instrumentation amplifiers, signal conditioning, oscillators, active filters, load and level conversions, and analog computing. There is also extensive coverage of circuit construction techniques, including circuit board design, grounding, input and output isolation, using decoupling capacitors, and frequency characteristics of passive components. The material in this book is applicable to all op amp ICs from all manufacturers, not just TI. Unlike textbook treatments of op amp theory that tend to focus on idealized op amp models and configuration, this title uses idealized models only when necessary to explain op amp theory. The bulk of this book is on real-world op amps and their applications; considerations such as thermal effects, circuit noise, circuit buffering, selection of appropriate op amps for a given application, and unexpected effects in passive components are all discussed in detail. *Published in conjunction with Texas Instruments *A single volume, professional-level guide to op amp theory and applications *Covers circuit board layout techniques for manufacturing op amp circuits.

Download or read book Low Power VCO Design in CMOS written by Marc Tiebout and published by Springer Science & Business Media. This book was released on 2006-01-25 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work covers the design of CMOS fully integrated low power low phase noise voltage controlled oscillators for telecommunication or datacommuni- tion systems. The need for low power is obvious, as mobile wireless telecommunications are battery operated. As wireless telecommunication systems use oscillators in frequency synthesizers for frequency translation, the selectivity and signal to noise ratio of receivers and transmitters depend heavily on the low phase noise performance of the implemented oscillators. Datacommunication s- tems need low jitter, the time-domain equivalent of low phase noise, clocks for data detection and recovery. The power consumption is less critical. The need for multi-band and multi-mode systems pushes the high-integration of telecommunication systems. This is o?ered by sub-micron CMOS feat- ing digital ?exibility. The recent crisis in telecommunication clearly shows that mobile hand-sets became mass-market high-volume consumer products, where low-cost is of prime importance. This need for low-cost products - livens tremendously research towards CMOS alternatives for the bipolar or BiCMOS solutions in use today.

This book was released on 2007-05-08 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is hardly a profound observation to note that we remain in the midst of a wireless revolution. In 1998 alone, over 150 million cell phones were sold worldwide, representing an astonishing 50% increase over the previous year. Maintaining such a remarkable growth rate requires constant innovation to decrease cost while increasing performance and functionality. Traditionally, wireless products have depended on a mixture of semicond- tor technologies, spanning GaAs, bipolar and BiCMOS, just to name a few. A question that has been hotly debated is whether CMOS could ever be suitable for RF applications. However, given the acknowledged inferiority of CMOS transistors relative to those in other candidate technologies, it has been argued by many that “CMOS RF” is an oxymoron, an endeavor best left cloistered in the ivory towers of academia. In rebuttal, there are several compelling reasons to consider CMOS for wi- less applications. Aside from the exponential device and density improvements delivered regularly by Moore’s law, only CMOS offers a technology path for integrating RF and digital elements, potentially leading to exceptionally c- pact and low-cost devices. To enable this achievement, several thorny issues need to be resolved. Among these are the problem of poor passive com- nents, broadband noise in MOSFETs, and phase noise in oscillators made with CMOS. Beyond the component level, there is also the important question of whether there are different architectural choices that one would make if CMOS were used, given the different constraints.
