Squeezing Cost While Raising Quality

I was working on a new connector design for 50 ohm impedance-matched coax connectors for Automotive Digital Satellite Radio receiving at 2.33 GHz. This application was very sensitive to electrical performance, with low insertion losses (i.e. a low impedance discontinuity, low dissipation factor, and low reflections from impedance mismatches), but was also very cost sensitive. The target electrical performance was …

Flexible Chips Take Intelligent Fashion To The Catwalk

Flexible electronics have been around for years. Decades ago, car manufacturers started using flexible printed-circuit boards (PCBs) behind vehicle dash panel instrumentation clusters, but they were large and clumsy. For today’s design engineers, the Holy Grail of electronic component flexibility would be a chip that can bend and stretch like human skin. Most electronic systems and components are still rigid …
