What about 'The Art of Electronics', by P.Horowitz and W.Hill? Not only it goes through many real circuits and systems, it has questions like: 'What is wrong with this circuit?' at the end of every chapter. It is a bit light on math (which in my view is a weakness) but has a lot of engineering insight.
