Circuit Model of Photo-Controlled Surface Negative Impedance Transistor and Its Simulation
光电负阻晶体管PNEGIT的电路模型和模拟

A circuit model of Photo-Controlled Surface Negative Impedance Trans istor (PNEGIT) is presented.Based on the mathematical model of a gate-controlled transistor and the circuit model of solar cells, a device with surface and body recombina tions is described for the first time by a circuit model,which provides a m ethod for studying PNEGIT,Surfac e Negative Impedance Transistor (NEGIT) and their applied circuits.Results of s imulation and experiment are compared.
