The proposed circuits are key points in a battery-life-free RFID tag, by sensing the charge stored in a supply capacitor, and enabling the rest of the system when enough charge is available. In comparison to previous published circuits, the average current of our circuits is one order of magnitude lower. The average current consumption for our solutions is below 100 nA, for a supply voltage between 2.5 V and 3.3 V. In addition, we have proposed some modifications to the best published results; and diminished the power consumption one order of magnitude. | URI: | http://hdl.handle.net/10553/49677 | ISBN: | 0769526098 | DOI: | 10.1109/DSD.2006.94 | Fuente: | Proceedings of the 9th EUROMICRO Conference on Digital System Design: Architectures, Methods and Tools, DSD 2006 (1690096), p. 625-629 |
