IC Design Interview 2: Miller Op-Amp

I sprinkle Miller op-amps around my designs. They are useful to drive low capacitance internal signal lines. They make fine buffer amplifiers. Many IC designers seem to be dead set against them, but I think they do have their place. Even those engineers who would never use a Miller op-amp and spend a fair amount of time during the interview explaining why no one should ever use them will expect good knowledge of the structure, theory, and practice of design and use of the lowly Miller op-amp.

These are my interview notes so they only cover the things I tend to forget, i.e., the equations.

I am hoping to have interior trailer lights ready for next week.
