Report：Cross-couple DTMOS rectifier with Floating sub-circuit using 65nm SOTB CMOS technology for uW RF Energy Harvesting
October 22, 2018
Abstract This paper presents a design and evaluations of cross-couple rectifier with floating sub-circuit using DTMOS (Dynamic Threshold MOSFET) in uW input power. The circuit was fabricated in 65nm SOTB CMOS technology and evaluated in wide range of frequency, with various loads and small input power.
The proposed circuit shows a better performance as compared to the conventional DTMOS rectifier. When input power is higher than -12 dBm, PCE of the proposed circuit becomes more than 20% and reaches maximum 33% at -5 dBm.
