Printed electronics is considered a promising technology for low-cost electronics due to its low cost per unit area, typically offered at the expense of degraded performance. Using a combination of synthetic nanoparticles, organic semiconductors, and novel printing techniques, we demonstrate a range of printed electronic devices including transistors, passive components, and a range of chemical sensors...
In this work, the high frequency (RF) performance of FinFETs is investigated in detail using a two-level parasitic model comprising outer and inner parasitic capacitances in addition to parasitic series resistances. Use of scaling relations of these parasitic capacitances with numbers of fins and fingers allows extraction of these elements. Next, by defining a series of reference surfaces, each associated...
A fully integrated CMOS receiver consisting of an LNA and a mixer has been designed and fabricated in IBM BiCMOS 7WL 180 nm technology. An on-chip balun loading the second stage of the LNA was implemented as well for single-to-differential conversion. The receiver was developed for high performance wireless local positioning systems and excellent experimental results were demonstrated: a conversion...
Modern wireless communication standards, e.g. UMTS, are making use of modulation schemes, resulting in signals with high levels of peak-to-average power ratio (PAR). For example, the W-CDMA signal used in UMTS-standard has typical PAR levels above 6 dB. Conventional single-ended power amplifiers will result in low levels of average efficiency, if they were implemented in the transmitters of such communication...
In this work we present a fully integrated BiCMOS RF-receiver. The receiver comprises an LNA and a mixer. The most challenging aspects of the design were the high gain and an extremely low noise figure specified by RESOLUTION. The target was to achieve an integrated LNA and mixer showing at least 25 dB voltage conversion gain and overall noise figure less than 4 dB under minimum power consumption...
This work demonstrates an integrated low noise, high gain receiver targeted for wireless local positioning applications. The receiver is implemented in a 0.18 mum SiGe BiCMOS technology. With a single ended input and differential output the receiver comprises a two stage bipolar low noise amplifier with integrated on-chip transformer for single to differential conversion and a double balanced mixer...
