Designing organic and inorganic ambipolar thin-film transistors and inverters: Theory and experiment

► Analytical models were presented describing the voltage transfer characteristics (VTC) of CMOS and ambipolar inverters. ► The presented models provide insights into the electrical characteristics of both inverter technologies. ► The models were compared to experimentally realized inorganic and organic ambipolar transistors and inverters. ► The models were used to investigate the effect of different transistor parameters on the static noise margin. ► A comparison shows that the SNM of ambipolar inverters can reach 75% of the CMOS inverter's SNM.
