Embodiment Construction
[0071] Further description will be given below in conjunction with the accompanying drawings and embodiments.
[0072] figure 1 It is the equivalent circuit structure of the simulation model of the junction field effect transistor of an embodiment. The simulation model of the junction field effect transistor includes a core field effect transistor model M1, a first diode model D_GD_para, a second diode model D_GS_para, a third diode model D_BD_para, and a fourth diode model D_BS_para.
[0073]The current and voltage characteristics of the core field effect transistor model M1 are fitted using the parameters of BSIM3 / BSIM4. BSIM3 / BSIM4 is a circuit simulation standard developed by the University of California, Berkeley. Starting from the third generation of BSIM3, the simulation standard is based on the physical model, based on quasi-two-dimensional analysis, and solves the physical characteristics of the device when it is working. In order to improve the accuracy in specifi...
