This paper highlights the importance of energy harvesting in high-value asset monitoring applications involving use of active RFID tags. The paper begins by highlighting advantages of active tags including improved range and read rate in electromagnetically unfriendly environments. Although a battery can substantially improve performance, it limits maintenance-free operational life. Therefore, harvesting...
This paper focuses on effective system modeling and implementation of a dc-dc buck converter with a digital controller. Two methods are systematically followed to design a two pole, two zero proportional-integral-derivative (PID) controller. Method one uses a traditional design by emulation, where compensator poles and zeroes are chosen based on the uncompensated loop response to yield sufficient...
