A Static Model of Optically Controlled PHEMT in PSPICE

We presented a static model of converted optically controlled PHEMT. This is a four port model in which port P is used to deal with light signal. The model could simulate the influence of the imported light on the device's output current under different light power and different wavelength. Using PSPICE to simulate the DC characteristics of optically controlled PHEMT, the simulation results show good agreement with experimental data.
