Saravanan Yuvaraja, et al.,"Fully Integrated Organic Field‐Effect Transistor Platform to Detect and to Quantify NO2 Gas." physica status solidi (RRL)–Rapid Research Letters, 2020, 2000086. Herein, the gas sensing characteristics of PDVT‐10 organic field‐effect transistor (OFET) devices are explored and integrated to build a compact analog‐to‐digital converter (ADC) gas detection system. The electrical characteristics of the pristine PDVT‐10 OFET exhibit I on/I off ratio and threshold voltage as 104 and −12 V, respectively. Through the coating of a metal‐organic framework (MOF) on the surface
