Digital Electronics
Everything a chip is built from, from the ground up. Number systems and binary arithmetic, logic gates and Boolean algebra, Karnaugh maps, combinational and sequential circuits, and finite state machines. Start here if you are new to digital design, or use it to refresh the fundamentals interviewers still test.
