We have fabricated a full-wave rectifier using fully depleted amorphous In-Ga-Zn-O thin-film transistors (TFTs). The rectifier is composed of four TFTs, and it rectified 13.56-MHz wireless input from a 200-mW commercial RFID reader/writer. We also have analyzed an output voltage and an operation frequency of the fabricated rectifier.
