Using one binary oxide, a fully transparent thin-film transistor (TFT)-based transceiver circuit is presented. The proposed transceiver circuit is fabricated entirely using an atomic layer deposition process. Moreover, the proposed circuit presents two modulation schemes: frequency shift keying and ON/OFF keying. The fabricated TFTs exhibit saturation mobility, threshold voltage, a subthreshold swing, and an ON/OFF ratio of 18.2 cm2 V−1 s−1, 0.9 V, 419 mVdec−1, and 109 times, respectively. Finally, the circuit functionality is demonstrated by the word “KAUST” as a Morse code.
