Intel researchers demo RF energy harvester
Articles 1/26/2009 Post a comment
Using low-lost circuitry based on a Texas Instruments MSP430 microcontroller, researchers at Intel Labs have devised an RF energy-scavenging platform that can harvest 60 microwatts - sufficient to drive many remote sensing applications - from a TV transmission tower at a distance of 4.1 km.
Using op-amps in the precision signal path
Articles 1/25/2009 3 comments
In systems where a digital sensor is interfacing to a processor, it will often fall to a digital engineer to design the complete signal path. So what are the key analog phenomena that need to be managed in order to produce a high-precision signal path with a single-supply op amp?
