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?
NEC : 16-bit flash MCUs feature an LCD controller-driver
Articles 1/16/2009 Post a comment
NEC has developed twelve 16-bit all-flash microcontrollers (MCUs) with on-chip LCD driver, optimized for the fields of handheld healthcare diagnostic instruments such as blood glucose meters, building utility meters for the gas/water/electricity markets, and FA equipment.
Allegro : Buck regulator IC achieves high switching frequency
Articles 1/15/2009 Post a comment
The A4403 from Allegro MicroSystems Europe is a 3-A buck regulator IC which uses a valley current-mode control scheme to offer very low switch-on times, making it attractive for applications that require high switching frequencies combined with high input voltages and low output voltages.

The ultra-low-power MSP430FE42x2 MCU solutions from TI are designed to reduce the electronic bill of materials for single-phase electricity metering applications to the $1 range.
These days, I often code design equations for filter circuits directly into sequences of Excel cells
The introduction of the solar boat is necessary to preserve our planet, which is mainly covered by water; the autonomous drive option is a pleasant alternative
Leading up to APEC have been a slew of new introductions by various suppliers. I wanted to highlight some of that here on Planet Analog for your information
Could a 16-bit SAR converter application reach a dynamic range of 125 dB at 600 kSPS?
My ‘gut feel’ as an Electronics Engineer tells me that the need for more adequate and intensive pilot training is a strong possibility
