| Abstract: | In order to detect the dynamic characteristics of OSIT（organic static induction transistor）,we designed a micro-current detection circuit.The detection current range is 10-9 ～ 10-6 A,and the frequency range is 20 kHz.According to the electrical parameters of the CuPc organic thin film static induction transistor we made,we establish a small-signal equivalent circuit to analysis its characteristics,and then simulate it.The simulation results and the test results are basically coincidence,it indicates that the small-signal detection circuit and the equivalent circuit are feasibility.In addition,according to simulation results,we provide some suggestions to improve the dynamic performance of the device：reduce the inter-electrode capacitance or increase the electrical conductivity. |
