Biomechanical Energy Harvester Converts Human Motion Into Electricity
September 4, 2008 7:22 am | by Jason Lomberg, Technical Editor | Blogs | CommentsThe inherent weakness of any portable device is its isolation from a constant power source, such as electricity. Thus, battery technology has evolved alongside the iPod and laptop computer. But batteries themselves are inefficient, because they either deplete themselves, or in the case of rechargeables, require electricity supplied from a power grid. But what if you could harness the energy produced by the natural motion of the human body? Bionic Power is endeavoring to accomplish that with its “Biomechanical Energy Harvester.”

SMH: Direct RF Sampling with High Performance ADC
August 29, 2008 10:11 am | by Philip Pratt, Texas Instruments | Articles | CommentsPreviously analog-to-digital converters (ADC) at high input frequencies were limited in usefulness due to distortion and noise performance. Today, however, ADCs can provide nearly 9.5 bits of effective number of bits (ENOB) at radio frequencies (RF) of 1 GHz with signal bandwidths greater than 200MHz. Such performance at high frequencies eliminates a mixer stage, simplifying receiver design to improve overall system performance.
