I give a thumbs up for Designing Analog Chips - I found it really helpful and interesting, and it's free online at the above link.

And if you're interested in 1970s-era digital chips, I recommend Mead and Conway's "Introduction to VLSI systems" at http://ai.eecs.umich.edu/people/conway/VLSI/VLSIText/VLSITex...
