Energy harvesting ic rf.
E peas aem40940 rf energy harvesting ic is an integrated ambient energy manager aem that can extract ac power from a high frequency 868mhz 915mhz or 2 45ghz rf input simultaneously storing energy in a rechargeable element and supplying the system with two independent regulated voltages.
Analog devices offers a wide range of ultra low power ics for energy harvesting applications.
E peas aem40940 rf energy harvesting ic is an integrated ambient energy manager aem that can extract ac power from a high frequency 868mhz 915mhz or 2 45ghz rf input simultaneously storing energy in a rechargeable element and supplying the system with two independent regulated voltages.
Similarly for thermal energy harvesting it has an ic that extracts dc power from a thermoelectric generator and for vibration energy an available ic extracts power from a mechanical harvester.
The ic can manage poorly regulated sources such as energy harvesting devices with output levels ranging from 1µw to 100mw.
The device also includes a boost regulator circuit for charging the cell from a source as low as 0 75v typ.
There the energy can be stored in a capacitor connected to vcap or fed to the boost converter pcc210.
E peas rf energy harvesting ic solution aem40940 is an integrated energy management subsystem integrating a rectifier that extracts ac power from ambient rf waves to simultaneously store energy in a rechargeable element and supply the system with two independent regulated voltages.
E peas aem30940 rf energy harvesting ic is an integrated ambient energy manager aem that can extract dc power from a piezo generator a microturbine generator or any other high frequency 868mhz or 915mhz rf input simultaneously storing energy in a rechargeable element and supplying the system with two independent regulated voltages.
The aem40940 is designed to to extend battery.
The general layout of an rf energy harvesting system consists of a receiving antenna with a suitable design a rectifier and a dc dc circuit.
The boost converter defaults to 3 3v output but can be adjusted by adding resistors to vset.
Where p i are the powers in transmission and reception the latter being the most interesting to evaluate the energy harvesting power supply g i are the gains of the two antennas λ the rf wavelength and r the distance between the two antennas.
E peas rf energy harvesting ic solution aem30940 is an integrated energy management subsystem that extracts dc power from ambient rf signal to simultaneously store energy in a rechargeable element and supply the system with two independent regulated voltages.
Rf energy is fed into the device where it reaches the rf to dc converter ic pcc110.
