This paper presents a novel iterative non-breakdown rectifier topology which would practically solve the rectifier's early breakdown problem in multi-sine wireless power transmission (WPT) for biomedical application. The proposed rectifier holds an iterative topology which can extend the reverse breakdown voltage limitlessly with its forward threshold voltage remains. It keeps high conversion efficiency...
This paper proposes a triple-band rectifying circuit for ambient RF energy harvesting, which can be served as a power supply for the central unit in Wireless Body Sensor Networks (WBSN). It fully utilizes the RF energy in ambient and converts it into DC power with high efficiency. It covers the public telecommunication bands of GSM-900, GSM-1800 and UTMS-2100, which are measured to hold the major...
An efficient and successful multi-channel rectifier for ambient RF energy harvesting has been designed and evaluated at GSM-1800 and UTMS-2100 bands. This design could sufficiently enhance the RF-to-DC power conversion efficiency (PCE) in weak signal reception environment. The validity of the proposed design is verified by detailed experimental results, which indicate that a maximum PEC of 38.8% and...
Temperature and radiation tolerant electronics, as well as long life survivability are the key capabilities required for future NASA missions. Current approaches to electronics for extreme environments focus on component level robustness and hardening. Compensation techniques such as bias cancellation circuitry have also been employed. However, current technology can only ensure very limited lifetime...
