Yeah that's interesting if the model specifies nonzero CJO since I'm pretty sure that models varactor effects. Though it's probably an ideal varactor with infinite SRF... looks like that's true up to 100mhz at least.
Sort of... there are apparently major architecture differences in the few implementations not based on spice3, namely ltspice and xyce. LTspice seems to be essentially a custom x86-only JIT architecture but has almost no interesting original features aside from maybe a bit better performance in...
Ha well I'm a self-taught computer science guy with my day-to-day being predictably irrelevant discrete math, logic, type-theory sorts of things. Learning the linear algebra necessary for solving matrices for circuit simulation looks pretty "within reach". I should do that. I have no formal math...
I am doing a learning project by writing a simulation that includes capacitance and current flow amongst capacitors that may potentially be in parallel. I don't care about certain details yet - dissipation factor, frequency dependent effects, temperature. Tiny capacitences within diode junctions...
Indeed I'm aware of the ubiquitously self-referential jargon surrounding this subject. Maybe there's a reason... It's largely why I've resorted to asking such a general question.
I often encounter functions called "polynomial" in numerous fields. I don't see an obvious common trait other than that they're usually describing a real-valued continuous function. What aspects are typical or universal or distinct? What structures can be polynomial? Some sources say that...
