GaN based Power Devices Make Possible A New Paradigm in Power Conversion

March 25, 2009 8:30 am | by Michael A. Briere, Executive Scientific Consultant, ACOO Enterprises LLC, under contract to International Rectifier Corp. | Articles | Comments

From planar HEXFETs to TrenchFETs and superjunction FETs, silicon power MOSFETs have continued to evolve for the last 30 years to satisfactorily serve numerous markets. In fact, during that period, there have been some two orders of magnitude improvement in performance. However, this silicon power device is rapidly approaching maturity


Design Talk: Digital & Analog

March 25, 2009 7:16 am | Articles | Comments

Typically, industries use standards to improve product quality and enable component sharing across projects. In practice, such standards achieve wide acceptance since the synergistic effects provide significant benefits to the user community. The hardware and software industry is full of such standards, but there is an exception: the deeply embedded microcontroller market

Google Inc. Chief Executive Eric Schmidt and co-founders Larry Page and Sergey Brin maintained their traditional salaries of $1 last year even as the value of their combined stakes in the Internet search leader plunged by nearly $26 billion.


Feinstein Blocking Solar Development in Mojave

March 25, 2009 5:04 am | Product Releases | Comments

California's Mojave Desert may seem ideally suited for solar energy production, but concern over what several proposed projects might do to the aesthetics of the region and its tortoise population is setting up a potential clash between conservationists and companies seeking to develop renewable energy.


Sensor Zone: April 2009

March 24, 2009 1:25 pm | by Chris Warner, Executive Editor | Articles | Comments

For the last half-century, sensors based on the Hall effect have provided a low-cost, solid-state option for sensing any object that incorporates a magnetic field. Hall effect sensors are based on the discovery by Dr. Edwin H. Hall in 1879. He found that a thin conductive material, placed in a magnetic field, formed a difference in potential (voltage) at the opposite edges that was

World’s Cheapest Car Riles Environmental Groups

March 24, 2009 12:27 pm | by by Jason Lomberg, Technical Editor | Blogs | Comments

Tata Motors has unveiled the world’s cheapest car, with potential for a vast standard of living increase. And Greenpeace doesn’t like it. The same organization that supported a ban on chlorine in drinking water feels that the mass proliferation of cheap automobiles is a bad thing. Despite its eco-friendly 47 MPG rating, the Tata Nano is seen as a threat to the environment. Why? Because lots of people want to buy them.
