This paper reviews state-of-the-art approaches for galvanically isolated DC-DC converters based on radio frequency (RF) micro-transformer coupling. Isolation technology, integration level and fabrication issues are analyzed to highlight the pros cons of fully integrated (i.e., two chips) multichip systems-in-package (SiP) implementations. Specifically, different basic isolation technologies com...

CMOS deep N-well technology can eliminate the physical effects of NMOS transistors and reduce substrate noise and coupling in order to reach the NMOS channel. These properties result in better LO-IF and LO-RF isolations in a Gilbert micromixer. Two identical 0.18m CMOS downconversion micromixers (except at the RF input stage) with deep N-well or without deep N-well are fabricated in adjacent ar...

Recent studies from major network technology vendors forecast the advent of the Exabyte era, a massive increase in network traffic driven by high-definition video and high-speed access technology penetration. One of the most formidable difficulties that this forthcoming scenario poses for the Internet is congestion problems due to traffic volume anomalies at the core network. In the light of th...

Since the last comprehensive review by Otto Sticher on natural product isolation in NPR (O. Sticher, Nat. Prod. Rep., 2008, 25, 517), a plethora of new reports on isolation of secondary compounds from higher plants, marine organisms and microorganisms has been published. Although methods described earlier like the liquid-solid chromatographic techniques (VLC, FC, MPLC, HPLC) or partition chroma...

The POWER4-based p690 systems offer the highest performance of the IBM eServer pSeries line of computers. Within the general-purpose UNIX server market, they also offer the highest levels of concurrent error detection, fault isolation, recovery, and availability. High availability is achieved by minimizing component failure rates through improvements in the base technology, and through design t...

a filtering power divider/power combiner based on half mode substrate integrated waveguide technology for high power applications is proposed. this design includes one half mode substrate integrated waveguide cavity, one matched load, and four sections of quarter-wavelength transmission lines. the high isolation between output ports is obtained by combining the half mode substrate integrated wa...

Creators of new technologies seek to signal a message of novelty and improvement. Instinctively, many of us want to endorse the message and believe that this new technology will improve our lives. There is an intuitive desire to believe that a new technology is special and unique. Consequently, regulators, judges and scholars tend to look at each new technology in isolation. For example, schola...

This paper reports on an investigation into how base isolation can produce benefits for the architectural design of hospitals. If a relatively new technology such as base isolation can be coupled with interdisciplinary collaboration from the birth of a project, it seems possible to achieve an improvement not only in their seismic, but also in their architectural design. The methodology adopted ...

Background: The majority of adult cancer patients/survivors encounter social challenges (e.g., obtaining support, maintaining relationships, feelings isolation). This systematic review summarizes intervention studies addressing integration or connectedness issues among young- and middle-aged patients/survivors. Methods: We searched the PubMed, CINAHL, Web Science databases (January 2000–May 202...

In this work, OmniVision's second generation (Gen2) of small-pixel BSI stacking technologies is reviewed. The key features of this technology are hybrid-bond stacking, deeper back-side, deep-trench isolation, new back-side composite metal-oxide grid, and improved gate oxide quality. This Gen2 technology achieves state-of-the-art low-light image-sensor performance for 1.1, 1.0, and 0.9 µm pixel ...
