Abstract
Since organic thin film transistor (OTFT) provides simple and low cost processes, its application to the OTFT display has been studied. We developed an RC oscillator using organic thin film transistor and inverters with bootstrapping transistors. Device parameters were optimized by the simulation and OTFT RC oscillators were fabricated. The oscillator frequency and its dependence on resistance and bias voltage were studied. The organic TFT is adequate for low cost and simple process integrated circuits. The frequency of oscillation was simulated and measured. It is acceptable for low-cost microelectronic device and flat panel displays.
