| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | As one example realization of the synergistic energy harvesting concept, photovoltaic (PV)-assisted CMOS rectifier technology is demonstrated. An on-chip pn junction diode acting as a PV cell converts light energy to a dc bias voltage, which compensates the threshold voltage of the MOSFETs and enhances the RF to DC power conversion efficiency (PCE) of the rectifier especially under low input power conditions. Based on the physics-based analyses of the PV cell operation, symmetric PV cell structures for balanced biasing and non-silicide PV cell structures to further increase the bias voltages are proposed and improved efficiencies of the rectifiers are experimentally verified. | |
