Reddit reviews Designing Analog Chips

I was thinking about using Designing Analog Chips by Hans Camenzind along with The Art of Electronics by Paul Horowitz as a guide for projects to do. I also recognize its important to know to design digital electronics (even though it may not necessarily be my strength) and know how to do research if I do end up doing the PhD so I was also looking into these books: link 1, link 2, and link 3. Are there any other books I should look into?

I was always able to remember that last name because of his book. I wish I had met him when he was still around.

Wikipedia has a great intro article on this chip. Youtube also has at least a million great videos showing how to use the 555. This is a chip that as an EE you should absolutely know forwards and backwards. While it's less useful nowadays - thanks to microcontrollers that cost less than a few cents - it's still an amazingly useful chip that can time pretty much anything.
