摘要:Energy limitations are commonly considered as an essential constraint of wireless and mobile devices. Mobile phone needs to be charged frequently which is a time consuming process. Energy harvesting has appeared as a favorable technology to solve the problem of energy constraints in mobile phone. This work proposes a new architecture of Ultra Low Power Hybrid Energy Harvester (ULP HEH) that can be employed in wireless communication devices. The proposed architecture is utilizing three hybrid sources which are: Thermoelectric Generator (TEG), Radio Frequency (RF) and Vibration. TEG is depending on the variance of temperature between the surrounding environment and the heat resulting from the power losses in the device. Vibration is related to the vibrating sources like motor or shaking the device. Radio Frequency signals are on purpose radiated by broadcasting station antennas and cellular phone antennas. Having three hybrid sources will help to overcome the limitations of single source harvester. The ULP HEH will be firstly designed and then modeled to be simulated later by using PSPICE software and finally established in 0.13 �m CMOS technology. Verilog coding under Mentor Graphics will be used for coding the established ULP HEH and then for real time implementation it will be downloaded to Field Programmable Gate Array (FPGA). The expected result from this harvester is to achieve 4.2 V as an output voltage, which all new mobile phones are made to be compatible with, from input range of 20 mV- 500 mV with high efficiency and reliability.
