All,
I found the discussions regarding Paul Burridges' FSM design very
enlightening. I have a tangential question, though. Does Spice (LTSpice,
Circuitmaker, etc.) accurately model transistor operation at 40 MHz? My
understanding is that Spice uses an Ebers-Moll (sp?) simplification to model
some of the physical properties of a transistor. Does this model include
capacitances such as the miller effect that I read about in some of the
discussions?
Also, do the LTSpice and Circuitmaker models use the Spice models in the AC
analysis or some other small signal simulation (e.g. y parameters or h
parameters)?
Thanks,
C
