Linear Technology's AN47 "High Speed Amplifier Techniques" is my favourite document in this category. It is both nicely presented, and a great resource for high performance electronics:
The mark of just how good AN-47 is that, even in the age of the internet, it's still one of the best go-to guides on high speed opamp design and the attendant/surrounding challenges. Particularly concerning proper oscilloscope techniques for accurate measurements of high speed circuits.

And this: "The bit pushers have commented software; why not commented hardware?"
I can't help but be impressed at those manhattan style layouts.
And LTspice is extremely powerful for a free tool, if challenging to learn.
