| الملخص: | Wireless energy harvesting is the technique to gather the ambient
RF energy transmitted from a wireless router, radio broadcast, or
TV broadcast to power up a sensor network without any
interconnecting wires. In this project, a low RF power harvester
design is presented to harvest the ambient energy in order to power
a tag circuit. A matching circuit is designed to implement
maximum power harvesting from the antenna. The operation of tag
circuit is divided into two modes: active mode and standby mode.
The tag circuit only requires 5uA at 2.5v in standby mode; excess
energy will be stored in a buffer capacitor for accumulation until
full operation mode. The system operates in the 2.4 GHz band
require a minimum input RF power of -5dbm. |
