I've been burning alot of time learning electronics. This book isnt too bad for beginners, but I get way more understanding out of Behrad Razavi's stuff, he has lectures on youtube as well as a book which has way more worked examples. OTOH this book introduces more intricate concepts much more early which can be good for motivation if you dont let yourself get stuck on totally understanding them. For example he goes through a BPT schmitt trigger before he even shows the small signal model for BPTs.
