 Abstract-We present a DC model to simulate the static performance of electrolyte-gated organic field effect transistors. The channel current is expressed as charge drift transport under electric field. The charges accumulated in the channel are considered being contributed from voltage-dependent electric double layer capacitance. The voltage dependent contact effect and short channel effect are also taken into account in this model. A straightforward and efficient methodology is presented to
