High‐Gain Logic Inverters based on Multiple Screen‐Printed Organic Electrochemical Transistors

Abstract Organic electronic circuits based on organic electrochemical transistors (OECTs) are attracting great attention due to their printability, flexibility, and low voltage operation. Inverters the building blocks of digital logic (e.g., NAND gates) analog amplifiers). However, utilizing OECTs in is challenging resulting gain output levels. Hence, inverters capable operating at relatively supply voltages, yet offering high larger windows than respective input window desired. Herein, realized from poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate‐based designed explored, exhibiting gains, enlarged windows, tunable switching points. The inverter designs multiple screen‐printed a resistor ladder, where one OECT driving transistor while or two additional used as variable resistors ladder. inverters’ performances investigated terms gain, levels, point. Inverters, + / − 2.5 V an 1 V, that can achieve with ∼110% increment up 42 demonstrated.
