The achieved conversion gain by coarse gain control is between 4.8 dB–54.9 dB. The millimeter-wave receiver circuit is biased with a 1.2V supply voltage. The measured power consumption is 69 mW

Ultra high data rate CMOS FEs

The availability of numerous mm-wave frequency bands for wireless communication has motived the exploration of multi-band and multi-mode integrated components and systems in the main stream CMOS technology. This opportunity has faced the RF designer with the transition between schematic and layout. Modeling the performance of circuits after layout and taking into account the parasitic effects resulting from the layout are two issues that are more important and influential at high frequency design. Performaning measurements using on-wafer probing at 60GHz has its own complexities. The very short wave-length of the signals at mm-wave frequencies makes the measurements very sensitiv to the effective length and bending of the interfaces. This paper presents different 60GHz corner blocks, e.g. Low Noise Amplifier, Zero IF mixer, Phase-Locked Loop, A Dual-Mode Mm-Wave Injection-Locked Frequency Divider and an active transformed power amplifiers implemented in CMOS technologies. These results emphasize the feasibility of the realization 60GHZ integrated components and systems in the main stream CMOS technology

Crystal-Less RF Communication Integrated Circuits for Wireless Sensor Networks.

The evolution of computing devices has changed daily life significantly over the past decades, and it is still advancing towards pervasive and ubiquitous networks. At each step, the volume shrinks by 2-3 orders of magnitude while the functionality and computing power remains constant or increases. Wireless sensor networks (WSN) are perceived as the next big step of computing technology for a variety of applications, including environmental sensing, health monitoring, un-obtrusive surveillance and invisible labeling. With thin-film micro-battery technology and CMOS scaling, we can now envision complete sensor nodes with cubic-mm form factors. As node volume reduces, external components like a crystal frequency reference, which does not scale with frequency or process, becomes one of the bottlenecks of realizing cubic-mm WSN node devices. This dissertation covers several aspects of the energy and integration challenges associated with cubic-mm WSN nodes without crystal references. Several new compact and low-power RF circuits for the synchronization and communication of WSN nodes are proposed and discussed. A 60GHz antenna-referenced frequency-locked loop (FLL) using an on-chip patch antenna as both the radiator and the frequency reference has been demonstrated for RF synchronization. The FLL, targeting communication of non-coherent energy detection systems, provides adequate frequency accuracy without crystal references. A 10GHz ultra-wideband (UWB) crystal-less transmitter with an on-chip monopole antenna has also been demonstrated. It operates over the supply voltage range of a micro-battery; generate tunable pulse durations and center frequencies, and lives on an on-chip local decoupling capacitor only. A 1MHz temperature-compensated relaxation oscillator is also proposed in the dissertation for baseband data synchronization. With the modified RC network of the conventional relaxation oscillator, the transfer function of the network has a transmission zero, introducing an additional degree-of-freedom for temperature compensation design. Finally, a 60GHz transmit/receive (T/R) switch-less antenna front-end using an on-chip patch antenna is presented, which has an in-band isolation inherited from the standing wave pattern without implementing a T/R switch. The research projects have explored the circuit design techniques and system integration for cubic-mm energy-constrained devices, achieving both long lifetimes and small volumes for WSN applications.PhDElectrical EngineeringUniversity of Michigan, Horace H.

mm-Wave Systems for High Data Rate Wireless Consumer Applications

ISM spectrum at 60GHz has attracted attention for possible high-speed applications in wireless communications for well over ten years. However, no high volume applications have emerged. Despite progress in mm-wave ICs, the power and cost of these efforts have not reached the level needed for mass deployment. This paper summarises the ARC funded GLIMMR project which aims to remedy this situation by designing systems on silicon that have both low cost and low power. In particular, the paper presents design work done to date that indicate that silicon (particularly SiGe) is on the cusp of being able to provide economical mm-wave systems

Design methods for 60GHz beamformers in CMOS

The 60GHz band is promising for applications such as high-speed short-range wireless personal-area network (WPAN), real-time video streaming at rates of several-Gbps, automotive radar, and mm-Wave imaging, since it provides a large amount of bandwidth that can freely (i.e. without a license) be used worldwide. However, transceivers at 60GHz pose several additional challenges over microwave transceivers. In addition to the circuit design challenges of implementing high performance 60GHz RF circuits in mainstream CMOS technology, the path loss at 60GHz is significantly higher than at microwave frequencies because of the smaller size of isotropic antennas. This can be overcome by using phased array technology. This thesis studies the new concepts and design techniques that can be used for 60GHz phased array systems. It starts with an overview of various applications at mm-wave frequencies, such as multi-Gbps radio at 60GHz, automotive radar and millimeter-wave imaging. System considerations of mm-wave receivers and transmitters are discussed, followed by the selection of a CMOS technology to implement millimeter-wave (60GHz) systems. The link budget of a 60GHz WPAN is analyzed, which leads to the introduction of phased array techniques to improve system performance. Different phased array architectures are studied and compared. The system requirements of phase shifters are discussed. Several types of conventional RF phase shifters are reviewed. A 60GHz 4-bit passive phase shifter is designed and implemented in a 65nm CMOS technology. Measurement results are presented and compared to published prior art. A 60GHz 4-bit active phase shifter is designed and integrated with low noise amplifier and combiner for a phased array receiver.
