(2006), pp. 1681-1686.</i><br /><br />We propose a novel structure for a group-cross symmetrical spiral inductor (GCSI). The inductor has higher self-resonance frequency and quality factor, but the same dc inductance and layout area as a conventional symmetrical inductor. We compare measured data of the GCSI and conventional inductors to show the advantages of the new inductor structure.

Here, we report on our progress in developing materials, processes, and devices for the realization of ultralow-cost printed RFID tags. Using printed nanoparticle patterns that are subsequently sintered at plastic-compatible temperatures, low-resistance interconnects and passive components have been realized. Simultaneously, printed transistors with mobilities >10/sup -1/ cm/sup 2//V-s have been realized using novel pentacene and oligothiophene precursors for pMOS and ZnO nanoparticles for nMOS. AC performance of these devices is adequate for 135-kHz RFID, though significant work remains to be done to achieve 13.56-MHz operation.

The values of the inductors were found to be close to the design values. Inductors with 6 mil spacing were found to be closer to the design values than the 4 and 5 mil of spiral inductors. It may be because of the mutual inductor effect between the turns. Q values of the smaller inductor are comparable to the discrete values. Low-pass filters built using printed inductors between 100 and 400 MHz cut-off frequencies provided close to the simulated performances in which discrete component model were used Printed inductors on alumina substrates Har Dayal Quang Le Microwave Magazine, IEEE, Vol. 2, No. 2.

Proceedings. 4th International Conference on (2001), pp. 800-805.</i><br /><br />The recent aggressive downsizing of CMOS devices makes it potential to implement RF front-end in the CMOS process, but RF circuits have some special demands which the standard digital CMOS process does not consider: low noise, high linearity, high quality passive components. These demands present the main barriers to implement the RF front-end in CMOS process and need special efforts to get good performance.

A multilayer inductor design is described resulting in a high value of inductance at small dimensions. Consideration of manufacturing and reproduction tolerances is made. Finally measurement results on typical parameters describing a printed inductor are given.

Improved models for integrable lumped-element straight-line, single-loop, and spiral inductors, as well as for interdigitated and MIM capacitors, have been derived using numerical solutions of the inductance integral, basic microstrip theory, and network analysis. The broad experimental verification shows good agreement between models and experiments, with deviations of 5-10% up to 18 GHz. Besides the practical values and frequency range, losses of the lumped elements are presented CAD models of lumped elements on GaAs up to 18 GHz E Pettenpaul H Kapusta A Weisgerber H Mampe J Luginsland I Wolff Microwave Theory and Techniques, IEEE Transactions on, Vol. 36, No. 2.

The center frequency is insensitive to the thickness of the substrate. A miniature seven-pole narrow-band HTS bandpass microstrip filter has been designed, fabricated and tested for an astronomy observation application, which requires a center frequency at 610 MHz and 0.82% fractional bandwidth. The computed and measured results are found in excellent agreement.

(2001), pp. 557-565.</i><br /><br />An understanding of the high-frequency parasitic and packaging effects of passive surface-mounted devices (SMDs) can be gained from equivalent-circuit characterization of the device. We develop a circuit model which accurately characterizes the nonideal behavior of SMD inductors mounted on a printed circuit board (PCB), considering the device packaging and the interaction between board layout and component parasitics. The model is valid over a wide frequency band up to the first resonance of the inductor. The equivalent-circuit parameters are extracted in closed form from an accurate measurement of the S-parameters of the board-mounted SMD inductor, without the necessity for cumbersome optimization procedures normally followed in RF circuit synthesis. This procedure of measuring the component in its designed PCB environment is referred to as extrinsic characterization, in contrast to the conventional intrinsic characterization employed in RF bridges and LCR meters, which does not include the board layout effects. The developed closed-form model can be directly incorporated in commercial CAD packages, and thus, it simplifies the analysis of electromagnetic field behavior in PCBs, such as prediction of radiated emissions, signal integrity, and EMI Experimental equivalent-circuit modeling of SMD inductors for printed circuit applications K Naishadharn Electromagnetic Compatibility, IEEE Transactions on, Vol. 43, No. 4.
