Robust digital design in organic electronics by dual-gate technology

A comprehensive study of dual-gate organic thin-film transistors targeting more robust organic circuitry is performed. The difference between zero-V
_gs
-load and diode-load logic is studied and an optimized design for both is presented. This new design is used in 99-stage ring oscillators, to determine stage delays, and in 64 b RFID transponder chips yielding data rates of 4.3 kb/s.
