Hi everyone,
I have a problem with the simulation result for calculating N-CH Mosfet
capacitance (Cgs, Cgd, and Cdb).
In this simulation I tried to verify my manual calculation with the Spice
result using Multsim 11.0. But, the result in Multism simulation is quit
different either from the manual calculation or from Pspice/Hspice simulation.
Manual Calculation:
Multisim Simulation:
Setting Parameters in Multisim:
.DC from Multisim
>DC from PSPICE
From those results, it seems that Pspice gave a close value to the theoretical MOSFET calculation here. And I got messy result in Multisim.
Can somebody help me solving this problem?..is Multisim not as powerful as other spice software? or I just messed up with the parameters setting form Multisim and ended with the wrong answer?
