General Interest 

Math Notes for Power Electronics and other Electrical Engineering Areas. This is a work-in-progress; I would appreciate your comments and corrections. 

Output Resistance of a Common-Emitter Stage. I have had to figure this one so many times you would think I would remember. 

Modeling a complicated transfer function with a simple one: low-and high-frequency cutoffs. Spice example of the effects of low- and high-frequency cutoff

If I were to write a circuits book, I would introduce the ideal transformer first, and put the practical transformer in a later chapter.  Here is my introduction to the ideal transformer.
