The latest featured papers are available below. UltraCMOS® Semiconductor Technology Platforms: A Rapid Advancement of Process & Manufacturing For more than 20 years, Silicon-on-Sapphire (SOS) technology— an advanced form of Silicon-on-Insulator (SOI) processing—has been used in semiconductor manufacturing. Recently, SOS in the form of UltraCMOS® technology has been designed into highvolume applications that have made it the technology of choice for several demanding RF applications.

It supports all types of thermocouples with cold junction compensation and any type of RTD (resistance temperature detector) with resistances up to 4 kΩ for 2-, 3-, or 4-wire connection configurations. www.electronics-eetimes.com/en/Learning-center/ Virtual Antenna Technology: The Flexible and Off-the-Shelf Mobile Antenna Solution The fast pace of the wireless industry puts an enormous time-tomarket pressure on the engineering of every new mobile device. Being in the heart of every mobile product, the design of the RF front-end and in particular, the antenna, becomes especially cumbersome as every product currently requires a fully customized antenna. Fractus’ new Virtual Antenna technology has been conceived to address this particular issue, proposing a new standard antenna element, the miniature mXTEND Antenna Booster, to virtually replace every customized antenna in virtually every mobile www.electronics-eetimes.com/en/Learning-center/ Adaptive Cell Converter Topology Enables Constant Efficiency in PFC Applications Power Factor Corrected AC rectification has been addressed in a variety of ways over the past three decades; however, the wide variation of worldwide AC line has imposed significant design trade-offs. This paper explains how the Vicor PFM converter represents a breakthrough by analyzing the converter structure at three different levels of detail: in a classic bottom-up approach, three different “magnification factors” will be applied to the same structure. www.electronics-eetimes.com/en/Learning-center/ Cloud Security in Real Time As a director, principle, advisor, contributing writer and speaker focusing on cyber security I have reviewed a variety of solutions, few being able to address cloud security. This White Paper addresses faults in current cloud security solutions and specific methods of addressing them with validated case studies. The White Paper discusses an important paradigm shift needed if true cloud security is to be achieved. www.electronics-eetimes.com/en/Learning-center/ Power Supply Measurement and Analysis with DPOPWR Application Software Today’s power supply designers are faced with increasing pressure to achieve power conversion efficiencies of 80% and even higher. This application note explains how Tektronix’ DPOPWR power analysis software can help designers meet the demands for longer battery life and “greener” designs. www.electronics-eetimes.com/en/Learning-center/ www.electronics-eetimes.com Electronic Engineering Times Europe December 2013 51
