Wireless Technologies Circuits Systems and Devices by Krzysztof Iniewski


 

PREFACE to Wireless Technologies Circuits Systems and Devices

Superior ideas for wi-fi communications current a imaginative and prescient of expertise that’s embedded in our environment and virtually invisible, however current at any time when required.

From established radio strategies like the worldwide system for cell communications (GSM), 802.11, or Bluetooth to extra rising like extremely extensive band (UWB) or good mud motes, a standard denominator for future progress is underlying built-in circuit expertise.

Though the usage of deep-submicron CMOS processes permits for an unprecedented diploma of scaling in digital circuitry, it complicates implementation and integration of conventional radio frequency (RF) circuits.

The explosive development of ordinary mobile radios and radically totally different new wi-fi functions make it crucial to search out architectural and circuit options to those design issues.

Two key points for future silicon-based programs are scale of integration and low energy dissipation. The idea of mixing digital, reminiscence, mixed-signal, and RF circuitry on one chip within the type of system-on-chip (SoC) has been round for some time.

Nonetheless, the problem of integrating heterogeneous circuit design types and processes onto one substrate nonetheless stays. Due to this fact, the system-in-package (SiP) idea appears to be gaining acceptance as properly.

 

Whereas it’s true that heterogeneous circuits and architectures initially developed for his or her native applied sciences can’t be successfully built-in “as is” right into a deep-submicron CMOS course of,

one would possibly ask the query whether or not these features may be ported into extra CMOS-friendly architectures to reap all the advantages of the digital design and stream.

It isn’t predestined that RF wi-fi frequency synthesizers be at all times charge-pump-based phase-locked loops (PLLs) with voltage managed oscillators (VCOs), RF transmit up-converters be I/Q modulators, and receivers use solely Gilbert cell or passive continuous-time mixers.

Efficiency of contemporary CMOS transistors is these days ok for multiGHz RF functions. Low energy has at all times been vital for wi-fi communications.

With new developments in wi-fi sensor networks and wi-fi programs for medical functions, energy dissipation is turning into the primary situation.

Wireless sensor community programs are being utilized in vital functions in commerce, healthcare, and safety. These programs have distinctive traits and face many implementation challenges.

The requirement of lengthy working life for a wi-fi sensor node beneath restricted vitality provide imposes probably the most extreme design constraints.

This requires progressive design methodologies on the circuit and system ranges to handle this rigorous requirement.

Wireless programs for medical functions maintain an a variety of benefits over wired alternate options, together with ease of use, diminished danger of an infection, diminished danger of failure, diminished affected person discomfort, enhanced mobility, and decrease price.

 

Usually, functions demand experience in a number of disciplines, various from analog sensors to digital processing cores, suggesting alternatives for in depth {hardware} integration.

The ebook addresses state-of-the-art CMOS design within the context of wi-fi communication for rising functions: 3G/4G mobile telephony, wi-fi sensor networks, and wi-fi medical functions.

New thrilling alternatives in physique space networks, medical implants, satellite tv for pc communications, car radar detection, and wearable electronics are mentioned.

The ebook is a should for anybody critical about future wi-fi applied sciences. The ebook is written by high worldwide consultants on wi-fi circuit design representing each the built-in circuit (IC) business and academia.

The meant viewers is practising engineers in wi-fi communication discipline with some built-in circuit background. The ebook can be used as a really helpful studying and supplementary materials in graduate course curriculum.

The ebook is split into three totally different elements. Half I supplies a wi-fi system perspective. In Chapter 1, Ali Niknejad from Berkeley supplies a broad introduction to varied features of wi-fi circuit design.

In Chapter 2, researchers from the College of Pavia describe challenges in CMOS design for multistandard radios. Rising new UWB expertise and its CMOS/BiCMOS implementations are mentioned by Domine M. W. Leenaerts from NXP/Philips in Chapter 3.

Yorgos Palaskas and Ashoke Ravi from Intel introduce novel circuit options for multiple-input multiple-output (MIMO) expertise in Chapter 4. Danijela Cabric and Robert W. Brodersen from Berkeley attain even additional out into the long run in Chapter 5 by discussing potential architectures of cognitive radios.

Jan M. Rabaey and his group from Berkeley current an thrilling perspective of short-reach wi-fi alternatives in Chapter 6.

That is adopted by a complete evaluate of wi-fi transceivers for short-reach functions given by a gaggle from Eindhoven College of Know-how in Chapter 7.

Thrilling functions of wi-fi expertise to human physique are mentioned by a gaggle from IMEC in Chapter 8. To conclude the fi rst a part of the ebook, a analysis group from the College of Florida presents efforts towards integrating on-chip antennae on CMOS substrate in Chapter 9.

The second a part of the ebook offers with chip architectures and circuit implementation points. Robert Bogdan Staszewski from Texas Devices discusses revolutionary Digital Radio Processing™ chip structure in Chapter 10.

Low-noise amplifi ers (LNAs) are launched by Leonid Belostotski and James Haslett from the College of Calgary in Chapter 11. Design of LNAs for W-band functions is roofed by a gaggle from the College of Toronto in Chapter 12.

In Chapter 13, Vladimir Prodanov and Mihai Banu from MHI Consulting present an in depth therapy of energy amplifiers. Vikas Choudhary from PMC-Sierra and Krzysztof (Kris) Iniewski from CMOS cowl integer PLLs in Chapter 14.

Fractional PLLs for multiband synthesis are mentioned by a gaggle from Carleton College in Chapter 15. Jan-Wim Eikenbroek from Bruco describes fascinating design concerns for delta-sigma PLL utilized in Bluetooth functions in Chapter 16.

 

Lastly, to shut the second a part of the ebook, Sebastian Magierowski and his collaborators describe RFIC parametric converters in Chapter 17.

The third a part of the ebook offers with units and applied sciences used to manufacture wi-fi built-in circuits (ICs). John J. Pekarik from IBM presents a broad overview of CMOS expertise for wi-fi ICs in Chapter 18. Calvin Plett from Carleton College describes distributed results in RF CMOS chips in Chapter 19.

In Chapter 20, a gaggle from IMEC supplies deep perception into substrate coupling results that ceaselessly restrict chip efficiency.

Lastly, the final two chapters are dedicated to microelectromechanical programs (MEMS), an rising expertise that’s certain to change the way in which RF built-in circuits are constructed.

Mourad N. El-Gamal and his collaborators from McGill College describe integration of CMOS and MEMS applied sciences in Chapter 21, whereas Alexandru Müller and his collaborators concentrate on membrane-based MEMS programs in Chapter 22.

I wish to thank all contributors for his or her onerous work and carving out some valuable time from their busy schedules to write down their useful chapters.

I might additionally wish to thank the reviewers, editorial employees at CRC Press, and my colleagues who’ve reviewed parts of the manuscript.

Regardless of some challenges in integrating the fabric, there have been over 70 contributors altogether, placing collectively this ebook was one of the vital thrilling tasks in my life.
