Abstract
A very low power receiver and a transmitter are integrated on one silicon chip, thereby achieving a significant miniaturization of the tag with a long life time, and at the same time offering a significant reduction in unit price, despite requiring the use of a battery. The use of a backup battery helps overcome the range problem, the high cost of the reader, and the environmental problems associated with the emission of very strong magnetic fields.
