20-µW Operation of an a-IGZO TFT-based RFID Chip Using Purely NMOS
"Active" Load Logic Gates with Ultra-Low-Consumption Power

 

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
