Shockley's equation jfet
WebThe N-Channel JFET block uses the Shichman and Hodges equations to represent an N-Channel JFET using a model with the following structure: G is the transistor gate, D is the transistor drain, and S is the transistor source. WebThe minimum current (ID= 0) for a JFET occurs at pinch-off defined by VGS= VP, with VP being a negative voltage for n-channel devices and a positive voltage for p-channel JFETs. For gate-to-source voltages VGS is less than (more negative than) the pinch-off level, the drain current is also 0 A, as in the figure below (b).
