WebFor JFETs and depletion-type MOSFETs, Shockley’s equation is applied to relate the input and output quantities: For enhancement-type MOSFETs, the following equation is applicable: It is particularly important to realize that all of the equations above are for the device only!. They do not change with each network configuration so long as the WebThe Level 2 model is based on the Grove-Frohman equations (Frohman69), while the Level 3 model is based on empirical equations that provide similar accuracy and faster simulation times and better convergence. However, these models still do not provide good fits to the measured I-V characteristics of modern transistors.

WebVgs is about 3V for this transistor, so if we look at 5V on the graph Ids is 1 A, the Ids equation is: 1A = beta * (2V) 2 /2, so beta is 0.5 V 2 /A. If we look at 9V on the graph, Ids is 10 A, so the equation is 10A = beta * (6V) 2 /2, so beta comes out to 0.55 V 2 /A. So I'd feel comfortable punching in 0.5 for beta for this mosfet. WebBJT. There are two types of MOSFET and they are named: N-type or P-type. BJT is of two types and they are named as: PNP and NPN. MOSFET is a voltage-controlled device. BJT is a current-controlled device. The input resistance of MOSFET is high. The input resistance of BJT is low. Used in high current applications.
