Researchers from Qualcomm Detail New Studies and Findings in the Area of Solid State Electronics
June 3rd, 2011
According to recent research from San Diego, United States, "For fully autonomous implantable or body-worn devices running on harvested energy, the peak and average power dissipation of the radio transmitter must be minimized. Additionally, link symmetry must be maintained for peer-to-peer network applications."
"We propose a highly integrated 90 mu W 400 MHz MICS band transmitter with an output power of 20 mu W, leading to a 22% global efficiency-the highest reported to date for low-power MICS band systems. We introduce a new transmitter architecture based on cascaded multi-phase injection locking and frequency multiplication to enable low power operation and high global...
