Ltspice custom mosfet

MOSFET model Accuracy Caution available power MOSFET models range from trash to sophisticated. Spice does not have a built-in device model for a power MOSFET, so it requires a subcircuit to accurately describe one. Based on pioneering papers of 25 years ago, an accurate subcircuit requires a minimum of one diode plus two MOSFETs.

Nov 04, 2014 · LTSpice IV custom Mosfet Hi there, gentlemen, I’m an electrical engineering student and I’d like to simulate some basic electronic circuits, in LTSpice IV, in order to check the results of some theoretical exercises. LTspice therefore uses the simpler .MODEL statement to define the characteristics of a MOSFET. If using a 3rd party MOSFET model results in very slow simulation performance, it is probably because the model is defined using the .SUBCKT model and includes many parameters that are not necessary in getting an idea of the circuit performance. The .model statement defines a custom npn transistor with name npn105 and I s =10fA, =100, and Early voltage V A =100V.
