Crosstalk in Multi-Channel High-Speed ADCs

August 13, 2009 10:13 am | by Chuck Sanna, Product Marketing Engineer, Texas Instruments | Articles | Comments

In the push to increase bandwidth, range and sensitivity in wide bandwidth systems, multi-antenna and multi-sensor arrays are becoming increasingly popular. With each antenna or sensor requiring its own signal chain, many analog-to-digital converter (ADC) suppliers are integrating multiple high-speed ADCs into a single IC design.

A Bold Claim: Chevy Volt Gets 230 MPG

August 11, 2009 6:53 am | by by Jason Lomberg, Technical Editor | Blogs | Comments

Fool me once, shame on you. Fool me twice….well, you know the rest. When Raser Technologies claimed their re-jiggered Electric Hummer got 100 miles per gallon, I thought they fudged a few numbers. But for GM to claim 230 MPG for the Volt…well, that’s taking a trip to fantasyland, with magical goblins and unicorns.

July sees big jump in fuel efficiency of new cars

August 11, 2009 6:22 am | by Seth Borenstein, AP Science Writer | Blogs | Comments

Cars and light trucks sold in July got more miles per gallon than those sold in previous months, say researchers, who credit the Cash for Clunkers program. The average mileage for new vehicles rose from 21.4 miles per gallon in June to 22.1 mpg in July. That may not sound like much, but it's

Printable Solar Panels on the Cheap

August 6, 2009 12:40 pm | by by Jason Lomberg, Technical Editor | Blogs | Comments

One of the hottest trends in power is “conductive ink”—that is, ink that conducts electricity. Thus, we’ve seen the emergence of ultra-thin power solutions such as Fraunhofer Research Institution's silk-screened batteries. One of the variants is printable solar cells, a technology still in its infancy. But the US Air Force, in conjunction with Plextronics, has developed what they purport to be a “significant step forward in printing inexpensive solar cells.”

Thermal Management Strategies for Extreme 3U cPCI Embedded System Applications

August 5, 2009 6:47 am | by Barbara Schmitz, MEN Mikro Elektronik | Articles | Comments

As the cooling challenges of 3U CompactPCI (cPCI) embedded system applications multiply due to increased processing power, reduced package sizes and more hostile environments, new thermal management options and industry standards continue to evolve. Chip and board manufacturers have already done a vast amount of work to mitigate thermal management concerns.

Modules Simplify RF Designs

August 4, 2009 10:01 am | by Jon Titus, Senior Technical Editor | Articles | Comments

Ready-to-use wireless modules provide a way to quickly get a design "on the air" when engineers find RF circuits and communication protocols fall outside their areas of expertise. Even when engineers have RF experience, a module still might make sense from the perspective of saved time and money.

Low-Cost, High-Resolution Time-Measurement Application

July 16, 2009 10:11 am | by Jim Bartling, Microchip Technology | Articles | Comments

Time Domain Reflectometry (TDR) is a measurement of the impedance of a transmission line using the reflected energy of a pulse sent down that transmission line.  As a pulse is sent down a transmission line, it travels at the speed of light for the media it is in (typically, 60% to 80% of the speed of light in free space). As the pulse arrives at an impedance, mismatch energy is reflected back to the pulse source and arrives at a time

When to Use a Clock vs. an Oscillator
