CMOS power retriever for UHF RFID tags

A power retrieving circuit for a UHF RFID passive tag is proposed. The circuit is implemented with a 0.18μ m standard digital technology, and allows the empowering of the tag at more than 5 m from a 500 mW ERP interrogator

DC-DC CONVERTER FOR FUEL-CELLS AND PORTABLE DEVICES IN DIGITAL CMOS TECHNOLOGY

The manuscript discusses the design of an integrated DC-DC power converter in a digital 0.18 μm CMOS technology for fuel cells and portable applications. By means of a combined boost and switched-capacitor architecture and design optimization a suitable efficiency has been achieved without resorting to special process options and with a limited number of passive external components. The achieved results enable the implementation of a power-converter system for fuel-cell featuring low-cost and small size, as required by the market of portable device
