Abstract :
In this paper, we propose a pentacene organic thin-film transistor (OTFT) logic inverter circuit with a depletion mode load OTFT and an enhancement mode driving OTFT. It is confirmed that, with only two OTFTs, the minimum output voltage goes down to 0 V and it improves the noise margin characteristics. We believe that this scheme is a first but significant step for simple and reliable pentacene OTFT logic circuits.
