A Section of a MEMS Microphone Model
Here at Coventor, we are seeing a lot of interest in simulating noise, particularly for condenser microphones. With any transducer noise reduction is always a plus, and with microphones there are two specific applications that need low noise. One is where the microphone is positioned away from the sound source, such as in video calling or when using voice commands with tablet computers. The other is where multiple microphones are positioned in an array, to detect the direction of incoming sound or for noise canceling applications. read more…

LAKE WALES Fla.—Simplfying and popularizing microelectromechanical system (MEMS) design is the goal of the MEMS Design Contest announced yesterday (March 16) at the conference titled Data Automation and Test in Europe (DATE 2016, March 15 to 17, Dresden, Germany). More specifically, the contest encourages chip designers to add MEMS blocks to a chip design, using tools designed for the purpose.
Sponsored by Cadence Design Systems, Coventor, X-FAB and Reutlingen University, the contest will feature a special process design kit (PDK) that the winners will use to fabricate their MEMS chip at X-Fab. If interested attend the DATE session Launch of the Worldwide MEMS Design Contest.

It all started with smartphones and airbags. Design engineers began to integrate sensors in growing numbers into such systems to enable smarter performance. These applications mark the prelude to what Alberto Sangiovanni-Vincentelli, a professor at University of California, Berkeley, describes as a “sensory swarm” — a flood of heterogeneous sensors interfacing the cyber and physical worlds. By 2025, experts predict that the swarm could number as many as 7 trillion devices.
One of the first stages in the realization of this sensor-dominated world, the Internet of Things (IoT) requires technologies that can take on smaller form factors and operate on miserly power budgets. In their search to find sensing devices that can meet these requirements, designers have turned to micro-electromechanical systems, or MEMS. Before they can take full advantage of the miniaturization the technology offers and expand its role in the marketplace, engineers must be able to bridge the gaps between the MEMS, analog and digital design worlds. To do this, they will require a new set of tools.

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.
