This paper presents a passive UHF RFID tag with a dynamicVthcancellation （DVC） rectifier. In the rectifier, the threshold voltages of MOSFETs are cancelled by applying gate bias voltages, which are dynamically changed according to the states of the MOSFETs. The DVC rectifier enables both low ONresis...
