Abstract

A wide input range differential dual band RF energy harvesting system has been designed and presented for a battery less RFID applications. The proposed architecture includes an off-chip differential dual band antenna with differnetial dual band matching network followed by a CMOS cross coupled rectifier for RF-DC conversion which replaces a battery in several RFID applications. The proposed differential dual band matching network for the rectifier provides a peak efficiency of 60% at -12 dBm at 0.9 GHz and 64% at -16 dBm at 1.8 GHz. The proposed architecture achieves better efficiency for lower input power ranges from -20 dBm to 8 dBm which implemented using UMC 0.18μm CMOS Technology.
