Jim Williams wrote over 1600 pages of application notes on analog circuit design for Linear Technology. He also wrote several book chapters. I'm reading it all.The app notes are numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 17, 18, 21, 22, 23, 25, 28, 29, 31, 32, 35, 37, 43, 45, 47, 49, 55, 61, 65, 70, 72, 74, 75, 79, 81, 83, 85, 86, 89, 90, 92, 93, 94, 95, 98, 101, 104, 106, 112, 113, 118, 120, 122, 124, 126, 128, 131, 132, and 133.
