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 th...
