Oxide TFT rectifier achieving 13.56-MHz wireless operation with DC output up to 12 V

We have fabricated a rectifier using fully depleted amorphous In-Ga-Zn-O (a-IGZO) TFTs. The rectifier is composed of four TFTs and exhibited the rectification of 13.56-MHz wireless input from a commercial RFID reader/writer for the first time in oxide TFT devices. This result opens the possibility for wireless application of oxide TFTs.
