    Due to the aggressive scaling of metal-oxide-semiconductor field-effect transistors (MOSFETs) and silicon germanium SiGe heterojunction bipolar transistors (HBTs), silicon-based circuits operating above 100 GHz are becoming a reality. However, at present, most, if not all semiconductor foundries extract their transistor and passive device models from measurements conducted below 110 GHz and often ... View full abstract»

    Over several decades, advances in electronics miniaturization have been the engine for cost and performance gains in both military and commercial systems. More recently, breakthroughs in silicon-based technologies have accelerated the shift towards CMOS system-on-chip (SoC) solutions, combining complex radio-frequency (RF), analog and digital functionality. These advances, along with the introduct... View full abstract»

    The term radio frequency (RF) microelectromechanical systems (MEMS) refers to electronic devices with a moving submillimeter-sized part (beam, comb, disc, or ring), which provide RF functionality. Alternative definitions include bulk or surface micromachined devices, such as thin film bulk acoustic resonators (FBARs), which rely on energy transduction from the electrical energy domain to the acous...

    In this article, a high-efficiency saturated amplifier has been presented. This amplifier takes advantage of the nonlinear output capacitor to shape the voltage waveform. The nonlinear capacitor generates substantial second harmonic voltage with small higher order harmonics. Thus, using √2 times larger fundamental load and the proper second harmonic termination, the resultant voltage wavefo... View full abstract»

    The objective of this competition was to design, construct and demonstrate a working wireless communication architecture for software defined radio (SDR). The implementation had to contain at least one programmable device, the front-end analog RF circuitry, an analog-to-digital converter (ADC), and an analog output. This SDR student design contest required multiple disciplines. There was a need fo... View full abstract»

    By analyzing various output port layouts and transmission zeros resulting from high-order resonators, the appropriate order of the packaged circuit can be determined. The optimal packaged triplexer can reduce losses and improve isolation. Compared with tapped-line structures or coupled feeding lines, design processes can be simplified by employing distributed coupling techniques in the input and o... View full abstract»

    The quality of a communication system is mainly influenced by the sensitivity of the receiver. A critical receiver stage is the first amplifier [low noise amplifier (LNA)] that should have a low noise figure (NF) as well as sufficient gain to provide high sensitivity and also a high dynamic range to avoid intermodulation products from strong signals. The third-order intermodulation products have s... View full abstract»

    This continuation of my previous application note presents the general mechanism that causes common-mode coupling in mixers. Common mode coupling can increase the noise figure in receivers and/or transmitters. Also presented is a method of calculating the effect of vibration on phase noise in phase-locked oscillators (PLOs). When combined with the techniques presented in Part I, these methods allo...

    There is now, more than ever before, a need for technologies that enable the screening of people from a distance. A wide variety of weapons can be easily concealed under clothing and carried into crowded public sites to target national infrastructure, spread fear, and inflict mass murder and casualties. The most feared and devastating terrorist weapon is the suicide bomb or person borne improvised... View full abstract»
