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.

Design of High-Performance CMOS Voltage-Controlled Oscillators presents a phase noise modeling framework for CMOS ring oscillators. The analysis considers both linear and nonlinear operation. It indicates that fast rail-to-rail switching has to be achieved to minimize phase noise. Additionally, in conventional design the flicker noise in the bias circuit can potentially dominate the phase noise at low offset frequencies. Therefore, for narrow bandwidth PLLs, noise up conversion for the bias circuits should be minimized. We define the effective Q factor (Qeff) for ring oscillators and predict its increase for CMOS processes with smaller feature sizes. Our phase noise analysis is validated via simulation and measurement results. The digital switching noise coupled through the power supply and substrate is usually the dominant source of clock jitter. Improving the supply and substrate noise immunity of a PLL is a challenging job in hostile environments such as a microprocessor chip where millions of digital gates are present.

CMOS PLLs and VCOs for 4G Wireless is the first book devoted to the subject of CMOS PLL and VCO design for future broadband 4th generation wireless devices. These devices will be handheld-centric, requiring very low power consumption and small footprint. They will be able to work across multiple bands and multiple standards covering WWAN (GSM,WCDMA) ,WLAN(802.11 a/b/g) and WPAN(Bluetooth) with different modulations, channel bandwidths , phase noise requirements ,etc. As such, this book discusses design, modeling and optimization techniques for low power fully integrated broadband PLLs and VCOs in deep submicron CMOS. First, the PLL and VCO performances are studied in the context of the chosen multi-band multi-standard, radio architecture and the adopted frequency plan. Next a thorough study of the design requirements for broadband PLL/VCO design is conducted together with modeling techniques for noise sources in a PLL and VCO focusing on optimization of integrated phase noise for multi-carrier OFDM 64-QAM type applications. Design examples for multi-standard 802.111a/b/g as well as for GSM/WCDMA are fully described and experimental results from 0.18 micron CMOS test chips have demonstrated the validity of the proposed design and optimization techniques. Equally important the work describes techniques for robust high volume production of RF radios in general and for integrated PLL/VCO design in particular including issues such as supply sensitivity, ground bounce and calibration mechanisms. CMOS PLLS and VCOs for 4G Wireless will be of interest to graduate students in electrical and computer engineering, design managers and RFIC designers in wireless semiconductor companies.
