The following book is adapted from a chapter from my final year MEng project report at the University of York.
As a first pass I'll be copying the chapter more or less as-is into markdown format. Once all the content is there, I intend to improve it to make it more useful as an educational tool.
If you want to learn more about circuit simulation, I highly recommend Electronic Circuit & System Simulation Methods. At the time of writing, new paperbacks and ebooks are prohibitively expensive. Luckily there are some reasonably priced used copies available.
