“…The proposed IC only manages DC power. When AC power is generated from an ambient energy harvester, a rectifier circuit is required in front of the IC as derived in [20][21][22]. Much research has been done to improve the efficiency of rectifier and multiplier circuits, and in [23], a CMOS solution in a rectifier with a 0.18 µm technology was also implemented.…”

This paper presents an energy management integrated circuit for multiple energy harvesters in wireless body area network applications. The electrical power acquired from a single energy harvester around a human body is limited to micro watts, which is insufficient to drive a wearable electronic device. To increase this small amount, the energy from a number of harvesters has to be combined. By combining the energy from multiple distributed harvesters, each one producing negligible energy, significant energy for wearable devices can be obtained. In designing an energy management circuit for a wearable device, there are two issues to be resolved. The first is related to the power consumption of the circuit, and the second issue is related to the methods needed to manage the wide range of power that occurs as the energy input changes during harvesting. In this paper, an energy management circuit that resolves the two issues above is described. The circuit was integrated using 0.13 µm Taiwan Semiconductor Manufacturing Company complementary metal-oxide-semiconductor technology. The energy management circuit is designed to combine up to three sources of harvested energy with more than 90% operating efficiency over the entire power range of the energy harvested.

“…In that case the leakage current will become small. After reading some papers, we find the NMOS gate cross-connected bridge rectifier circuit [10], [11] can make the most negative potential of the antenna higher. The circuit is shown in figure 11.…”

The identification and modeling of different leakage components are very important for estimation and reduction of leakage power, especially low-power applications, such as RFID chip. This paper proposes a theory about leakage mechanism of RFID chip and proves the theory. The one contribution of the paper is the proposed theory about leakage mechanism of RFID chip. The other contribution is that it proves the differences between tape-out verification results and computer simulation results and that to what degree the differences occur for different circuits. And when the source potential is much lower than the substrate potential, tape-out verification results and computer simulation results have larger differences. The test results show that the actual leakage power increases 26.3 times compares with the computer simulation results' when the source potential is-750mV.

“…In some applications, the two functions should be applied simultaneously [7], [8]. Two practical applications are passive radio frequency identification (RFID) [9], [10] and wireless sensing system (WSN) [11], [12]. The role of information transfer in a RFID system is to detect objects, while its role in a WSN is to monitor the environment.…”
