This book was released on 2006-12-18 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio Frequency IDentification (RFID) stores and retrieves data using devices called RFID tags: objects attached to or incorporated into a product, animal or person which communicate with an RFID reader or interrogator. This book proposes a linear two-port model for an N-stage modified-Greinacher full wave rectifier, predicting the overall conversion efficiency at low power levels where the diodes are operating near their threshold voltage. Included is an experimental procedure to measure how impedance modulation in the tag affects the signal at the reader, and a useful tool for choosing the most appropriate impedances.

Download or read book A Passive RFID Transponder Using Harmonic Generation of Nonlinear Transmission Lines written by Fan Yu and published by . This book was released on 2012 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: In conventional passive RFID systems, the reader (interrogator) transmits signals to serve not only as an interrogation signal, but also as a power source to the tag (transponder). The continuous-wave (CW) signal to power up the passive tags inevitably couples to the receiver input as strong self-interference. In addition, the multipath reflection from the objects in view also results in strong in-band blocker. Both interfering signals present a major challenge to the reader's receiver design. To avoid this problem, a frequency multiplier is proposed to generate a harmonic of the interrogation signal, providing a unique response signal among the leakage from the transmitter as well as the incidental backscatter from the linear objects in view. Instead of using the active frequency multiplier or diode doubler, we propose a novel frequency doubling transponder utilizing harmonic generation by integrated nonlinear transmission lines (NLTLs), where the local data signal on the transponder is modulated onto the second harmonic of the interrogating carrier. By modulating the bias voltage of the NLTLs, the transponder is capable of Amplitude Shift Keying (ASK), Phase Shift Keying (PSK) and other similar coding schemes. This dissertation discusses (1) the introduction of passive RFID tag and (2) the harmonic generation theory of nonlinear transmission lines, (3) the design of reflective nonlinear transmission lines, (4) a study of the wireless link between the reader and the tag, (5) analog modulation of NLTL based capacitive sensor tag, as well as (6) digital modulation of NLTL based passive RFID tag. As a related effort, we also iii append a similar usage of taper-section NLTL in ultra-high frequency transmitters driven by baseband signal power. Finally, we summarize the our contribution and reflect on the possible future directions. iv.

Available in PDF, EPUB and Kindle. Book excerpt: New System-Level Techniques for Optimizing Signal/Power Integrity in High-Speed Interfaces--from Pioneering Innovators at Rambus, Stanford, Berkeley, and MIT As data communication rates accelerate well into the multi-gigahertz range, ensuring signal integrity both on- and off-chip has become crucial. Signal integrity can no longer be addressed solely through improvements in package or board-level design: Diverse engineering teams must work together closely from the earliest design stages to identify the best system-level solutions. In High-Speed Signaling, several of the field’s most respected practitioners and researchers introduce cutting-edge modeling, simulation, and optimization techniques for meeting this challenge. Edited by pioneering experts Drs. Dan Oh and Chuck Yuan, these contributors explain why noise and jitter are no longer separable, demonstrate how to model their increasingly complex interactions, and thoroughly introduce a new simulation methodology for predicting link-level performance with unprecedented accuracy. The authors address signal integrity from architecture through high-volume production, thoroughly discussing design, implementation, and verification. Coverage includes New advances in passive-channel modeling, power-supply noise and jitter modeling, and system margin prediction Methodologies for balancing system voltage and timing budgets to improve system robustness in high-volume manufacturing Practical, stable formulae for converting key network parameters Improved solutions for difficult problems in the broadband modeling of interconnects Equalization techniques for optimizing channel performance Important new insights into the relationships between jitter and clocking topologies New on-chip measurement techniques for in-situ link performance testing Trends and future directions in signal integrity engineering High-Speed Signaling thoroughly introduces new techniques pioneered at Rambus and other leading high-tech companies and universities: approaches that have never before been presented with this much practical detail. It will be invaluable to everyone concerned with signal integrity, including signal and power integrity engineers, high-speed I/O circuit designers, and system-level board design engineers.
