WiSpry’s New Antenna Tuner Enables Small Antennas to Deliver High Speed Connections across Worldwide Frequency Bands
WiSpry, Inc., the leader in tunable radio frequency (RF) semiconductor products for the wireless industry, today introduced its WS2018 Antenna Tuner – the industry’s lowest current consumption antenna tuner. The single-chip design WS2018 sits in the RF signal chain between the antenna and the front-end module of a mobile phone and provides superior transmit and receive chain impedance optimization over the full 824 MHz – 2170 MHz Global mobile frequency range.
Coventor has just released MEMS+ 2.1 for MATLAB Simulink and Cadence. MEMS+ 2.1 is a full update of MEMS+ 2.0 that includes a new MATLAB scripting interface. The new MATLAB scripting interface makes it possible to run simulations on a MEMS+ design directly from MATLAB, without involving Simulink. If you are a current MEMS+ customer you can download MEMS+ 2.1 from http://www.coventor.com/mems/download.html.
It is not necessary to uninstall or install MEMS+ 2.0 before installing this update. Coventor strongly advises all customer sites to install this update.
Abstract – In this paper we describe a novel tool for modeling the fabrication of MEMS and semiconductor devices, and show some examples of its application in the MEMS foundry business. The tool allows an accurate visualization of the step-by step creation of the final 3-D device geometry by using the 2-D layout and a description of the fabrication process. The novelty of the tool lies in its use of voxels (3-D pixels) rather than conventional 3-D CAD techniques to represent the 3-D geometry. The tool creates highly realistic, 3-D virtual prototypes of micro-fabricated devices.
3-D Process Modeling – A Novel and Efficient Tool for MEMS Foundry Design Support.
We describe a software tool for creating highly realistic, 3-D virtual prototypes of MEMS and semiconductor devices, and show how it has been applied to a MEMS SOI micromachining process. Two case studies demonstrate the value of virtual prototypes to a foundry: a 3-D design rule check that revealed a design error before mask tape out, and a process integration analysis that confirmed the suspected cause of a process failure.
