When I use LTSpice to create a MOSFET, it comes with a very high resistance when closed and a very low resistance when open. My guess is that the creators of LTSpice just took two values that are some kind of average for the values that most occur for transistors in the industry.
I guess I assumed that those creators would also use a time delay that is some kind of average of time delay for most such transistors. A certain amount of time passes between the time that one of the inputs changes and the time that the output changes. It may be a very small amount of time, but I'm sure it's nonzero.
However, my attempts to discover what that transistor delay is using LTSpice have met with failure. I've got a schematic where a transistor's inputs change and I've taken the time interval looked at from tens of nanoseconds down to hundredths of femtoseconds, and I still don't see any difference between the time the input changed and the time the output changed in response. This leads me to believe that the creators of LTSpice very possibly programmed that transition to be instantaneous. Is that true? If it's not true, how small is the delay between input change and output change for a typical transistor generated by LTSpice?
