Design of an efficient D-TV energy harvesting system for low-power applications

摘要

Collect energy from the surroundings is being biased to power-up devices in order to turn them self-sustainable. On the other hand, the spectrum resultant from the telecommunications tends to progressively increase and becomes wide-reaching, constituting an enormous opportunity to energy harvesting. This work aims to contribute with useful trends into the rectifier design to fulfil energy harvesting purposes. Three rectifiers are designed to collect D-TV spectrum and optimized to operate at low input power conditions. Measurements indicates 63% efficiency at -10.5 dBm input power with the Portuguese D-TV signal.
