Download or read book Wide band Low Noise Quadrature VCO in CMOS SOI written by Yipeng Wang and published by . This book was released on 2012 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a wide-band, low phase noise, low power Quadrature Voltage Controlled Oscillator (QVCO) designed in 0.18um CMOS Silicon on Insulator (SOI) technology. The 2.4 GHz ISM band QVCO achieves -124 dBc/Hz phase noise at 1MHz offset, 25% tuning range and 2.4mW power consumption under 1.1V supply. The SOI technology facilitates the design of high performance LC-VCO. High substrate resistance of SOI enables the fabrication of high Q on-chip inductor, which significantly improves VCO's phase noise performance. Moreover, an accumulation-mode (AMOS) varactor with reduced junction parasitic in SOI widens the VCO's tuning range. The Ring Injection Locked Frequency Divider (Ring-ILFD) demonstrates its wide locking range and low power consumption in high speed application. A combination of multiple injection and direct injection technique is used in this design to further enhance the locking range. The ILFD generates quadrature signal by halving the core VCO's output while strictly following its phase noise performance.

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.

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.

Download or read book Comparison of Low Power Wide Tuning Range 5 GHz Quadrature Phase LC CMOS VCO with Different Devices for Resonant Circuit written by Jo Yi Foo and published by . This book was released on 2005 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three low power 5 GHz LC cross-couple quadrature VCO with different resonant circuits were designed and fabricated in a standard 0.18[Mu]m single-poly, six metal layer mixed-signal CMOS process. Combination pairs of an active inductor, spiral inductor, junction varactor and MOScap are used to make the resonant circuit of the quadrature VCO in order to have the best possible performance circuit. Active inductor used in the design is a simple common-source amplifier structure with a PMOS feedback while the passive inductor used is a spiral inductor design using two of the highest level of metal in the process. Junction varactors used in the resonant circuit made use of the capacitance of NWELL and P-implant. All three VCO's have the same topology structure, which is the LC cross-coupled structure. This architecture is used in the design because of the simplicity while the cross-coupled featured will minimize the phase noise of the oscillator. Output drivers and pre-drivers are design to drive the VCO to a 50 ohm load. Phase noise, power dissipation, output power, spectrum accuracy and quadrature phase error are looked for and tested both in the simulation and on chip. Results of all three different types of resonant circuit VCO's are compared and discuss. All the circuits were fabricated through the MOSIS Educational Program.

Download or read book Low Power Wireless Communication Circuits and Systems written by Kiat Seng Yeo and published by CRC Press. This book was released on 2018-05-03 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing demand for extremely high-data-rate communications has urged researchers to develop new communication systems. Currently, wireless transmission with more than one Giga-bits-per-second (Gbps) data rates is becoming essential due to increased connectivity between different portable and smart devices. To realize Gbps data rates, millimeter-wave (MMW) bands around 60 GHz is attractive due to the availability of large bandwidth of 9 GHz. Recent research work in the Gbps data rates around 60 GHz band has focused on short-range indoor applications, such as uncompressed video transfer, high-speed file transfer between electronic devices, and communication to and from kiosk. Many of these applications are limited to 10 m or less, because of the huge free space path loss and oxygen absorption for 60 GHz band MMW signal. This book introduces new knowledge and novel circuit techniques to design low-power MMW circuits and systems. It also focuses on unlocking the potential applications of the 60 GHz band for high-speed outdoor applications. The innovative design application significantly improves and enables high-data-rate low-cost communication links between two access points seamlessly. The 60 GHz transceiver system-on-chip provides an alternative solution to upgrade existing networks without introducing any building renovation or external network laying works.
