CMOS Bridge Rectifier (CBR) using 0.18 Micron Technology for Energy Harvesting Applications
نویسندگان
چکیده
In this work, an input-powered AC/DC CMOS bridge rectifier (CBR) is proposed using 0.18 μm CMOS process. It is based on a simple bridge connected full wave rectifier, without an external dc voltage to turn-ON. The rectifier may be used for energy harvesting applications with a typical output of relatively low-amplitude input and low frequency of ac voltages. The proposed CBR achieves a maximum voltage efficiency of 96% with 1.0-V ac input amplitude and 50 Hz input frequency, delivering 1.22 mW of output power. The proposed CBR occupies an active area of 0.0054 mm2 that is at least 58.5 % smaller than other reported solutions.
