  • Abstract
    We fabricated the first RFID chip using amorphous InGaZnO (a-IGZO) thin film transistors (TFTs) on a glass substrate. Logic gates with low-consumption current (~1 nA) and steep on/off switching was also proposed. The logic circuit achieved small enough power consumption (20 μW) for wireless operation and a wireless operation of the RFID tag was demonstrated.
