This paper reports on efficient interfacing of typical vibration-driven electromagnetic transducers for micro energy harvesting. For this reason, an adaptive charge pump for dynamic maximum power point tracking is compared with a novel active full-wave rectifier design. For efficient ultra-low voltage rectification, the introduced active diode design uses a common-gate stage in conjunction with supply-independent...
This paper presents the analysis of the performance of charge pump, and the design strategy and efficiency optimization of 2.4GHz micro-power charge pump using 65nm CMOS technology. The model of the charge pump takes account of the threshold voltage variation, bulk modulation, and the major parasitic capacitor. Charge pump is sensitive to the input voltage swing and the actual input voltage swing...
