The Art of electronica is a good enough book but if I go to calculate nominal of Rs, Cs, connected to transistor on a simple relaxation oscillator things go wrong. I ask it in the hope if somebody stumble on a book with methods of calculating such things. By the way ngspice or any electronics simulator code is written on this base methods of calculation itself, is not it?
Mod edit: I moved this from Kicon 2020 talks but probably should just close it. Not sure it has a place here.

B) No, SPICE simulators (in transient mode) are using finite difference numerical methods to solve the network of nonlinear equations that represent the circuit. This is very different from the analytical analysis that you’d find in a textbook.
I got the point. Just needed some place to express an idea. I tried to express the idea to text editor emacs. Something was wrong. When I did it here some good happened after a while. A bit weird. Sorry.
