Available in PDF, EPUB and Kindle. Book excerpt: Abstract This chapter lays the foundation for the work presented in latter chapters. The potential of 60 GHz frequency bands for high data rate wireless transfer is discussed and promising applications are enlisted. Furthermore, the challenges related to 60 GHz IC design are presented and the chapter concludes with an outline of the book. Keywords Wireless communication 60 GHz Millimeter wave integrated circuit design Phase-locked loop CMOS Communication technology has revolutionized our way of living over the last century. Since Marconi’s transatlantic wireless experiment in 1901, there has been tremendous growth in wireless communication evolving from spark-gap telegraphy to today’s mobile phones equipped with Internet access and multimedia capabilities. The omnipresence of wireless communication can be observed in widespread use of cellular telephony, short-range communication through wireless local area networks and personal area networks, wireless sensors and many others. The frequency spectrum from 1 to 6 GHz accommodates the vast majority of current wireless standards and applications. Coupled with the availability of low cost radio frequency (RF) components and mature integrated circuit (IC) techn- ogies, rapid expansion and implementation of these systems is witnessed. The downside of this expansion is the resulting scarcity of available bandwidth and allowable transmit powers. In addition, stringent limitations on spectrum and energy emissions have been enforced by regulatory bodies to avoid interference between different wireless systems.

Available in PDF, EPUB and Kindle. Book excerpt: The operation of high frequency class-C alloy junction transistor oscillators is studied by use of a simplified version of the block-diagram representation for the transistor as developed by Bruun. For the simplified version of the block-diagram representation used, unilateral operation of the transistor is assumed. Expressions approximating the transistor time delay, peak ac input voltage, and the collector current pulse cutoff time are derived by use of the block-diagram equations. An analog circuit, derived from the block-diagram equations, is used to study the class-C operation of a typical alloy junction transistor, and the results of this study are found to compare accurately with the actual transistor operation.

Available in PDF, EPUB and Kindle. Book excerpt: The increase of consumer electronics and communications applications using Radio Frequency (RF) and microwave circuits has implications for oscillator design. Applications working at higher frequencies and using novel technologies have led to a demand for more robust circuits with higher performance and functionality, but decreased costs, size and power consumption. As a result, there is also a need for more efficient oscillators. This book presents up to date information on all aspects of oscillator design, enabling a selection of the best oscillator topologies with optimized noise reduction and electrical performance. RF and Microwave Transistor Oscillator Design covers: analyses of non-linear circuit design methods including spectral-domain analysis, time-domain analysis and the quasilinear method; information on noise in oscillators including chapters on varactor and oscillator frequency tuning, CMOS voltage-controlled oscillators and wideband voltage-controlled oscillators; information on the stability of oscillations, with discussions on the stability of multi-resonant circuits and the phase plane method; optimized design and circuit techniques, beginning with the empirical and analytic design approaches, moving on to the high-efficiency design technique; general operation and design principles of oscillators, including a section on the historical aspects of oscillator configurations. A valuable reference for practising RF and Microwave designers and engineers, RF and Microwave Transistor Oscillator Design is also useful for lecturers, advanced students and research and design (R&D) personnel.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The design of voltage-controlled Oscillators nowadays is all about being capable of operating at higher clock frequencies for the purpose of higher data rate, consuming less power for the purpose of longer battery life, and having better phase noise performance for the purpose of higher quality of wireless service and more efficient use of the available frequency spectrum since most of the wireless and mobile terminals that these VCOs work in are required to be able to operate in multiple RF standards to serve new generations of standards while being backward compatible with existing ones, leading to a demand for multi-standard multi-band radio operation that deals with high frequency RF signals that undergo different modulation schemes of different standards in different channels over a wide range of frequency band. A top-down system design from the PLL to the VCO is carried out to determine the specifications for a fully integrated dual-band voltage-controlled oscillator (VCO) designed for a Zero-IF WiMAX/WLAN receiver in a O.18tm CMOS technology with 1.8V supply voltage. A VCO employing a differential cross-coupled inductance-capacitance (LC) tank architecture is proposed to cover twice the desired frequency bands for WiMAX and WLAN standards in order to avoid load pulling between VCO frequency and incoming RF frequency. The switching between two bands is implemented by using two binary-weighted capacitor arrays while switching inside each sub-band is implemented by different digital control signal combinations for the binary-weighted capacitances. A phase noise of -120.7dB/Hz at 1MHz offset frequency is demonstrated for an oscillation frequency of 4.84GHz. The average power consumption of this VCO is 8.1mW. This VCO is developed as an IP (Intellectual Property) to be used in a fully integrated CMOS multi-standard WiMAX/WLAN radio allowing seamless roaming of handheld mobile devices between hotspots in future Wireless Metropolitan Area Network (WMAN). To compare the performance of ring oscillators to that of LC tank oscillators, the designs of two three-stage multiple-pass voltage-controlled ring oscillators with dual-delay paths are demonstrated where the differential delay cell utilizes both the primary loop delay and the negative skewed delay to increase the frequency of oscillation substantially and retain or even increase tuning range. Their phase noise performance is also improved by switching in and out the transistors periodically. In design I, the covered frequency range is from 0.74 GHz to 1.96 GHz, which translates to a tuning range of 90 % A phase noise of -104.995dBc/Hz is demonstrated for an oscillation frequency of 1.8535 GHz. Each stage draws a current of 4.963mA on average from a 1.8V power supply, resulting in a power consumption of 26.8mW. In design II, the covered frequency range is from 1.0478 GHz to 2.0022 GHz, which translates to a tuning range of 63%. The frequency-voltage curve is almost a perfect linear curve for V between OV and 0.9V. A phase noise of -110.O45dBc/Hz is demonstrated for an oscillation frequency of 2.00216 GHz. Each stage draws a current of 10.179mA on average from a 1.8V power supply, resulting in a power consumption of 55mW.

This book was released on 2012 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: With rapid development in the area of RF and wireless communication, the interest in frequency synthesizers has grown rapidly in the last few years. Frequency synthesizer is used for local oscillator (LO) generation. In this thesis, our aim is to explore high-frequency low-power LO generation in CMOS technology. We focus on three most power-hungry blocks in a frequency synthesizer, which dominate the total power consumption due to their high-frequency operation, namely voltage-controlled oscillator (VCO), frequency divider and frequency multiplier, as these circuits are the bottleneck to achieve the above mentioned aim. Through reducing their power consumption, the total power consumption of the frequency synthesizer can be reduced significantly. Moreover, the phase noise of the frequency synthesizer is significantly dependent on the VCO and the frequency multiplier. These novel ideas are implemented in a 24-GHz frequency synthesizer. These designs should help those IC designers, who may be considering improving the performance of transceiver.
