Abstract

A digital circuit using polymer thin-film transistors on polyester substrate is presented. The circuit consists of 171 transistors and converts a parallel word of four bits into a serial bit sequence by use of gates and flip-flops with level shifters. The integrated clock generator runs at oscillation frequencies of approximately 200 Hz with supply voltages of -25 V/+12 V. The polymer poly(3,3´´-dihexyl-2,2´:5´,2´´-terthiophene) (PDHTT) is used as semiconducting material. Measurement results for the circuit demonstrate that PDHTT can be used for digital polymer circuits.
