Abstract

A micro-power active-RFID LSI with an all-digital RF-transmitting scheme achieves experimental 10-m-distance communication with a 1-Mbps data rate in the 300-MHz frequency band. The IC consists of a RF transmitter and a power-supply circuit, which controls the energy flow from the battery to the IC, and offers intermittent operation of the RF transmitter. The IC draws 1.6 μA from a 3.4-V supply and is implemented in a 0.2-μm CMOS in an area of 1 mm². The estimated lifetime of the IC is over ten years with a micro-size battery.
