Cramming More Components Onto Integrated Circuits
TL;DR: Integrated circuits will lead to such wonders as home computers or at least terminals connected to a central computer, automatic controls for automobiles, and personal portable communications equipment as mentioned in this paper. But the biggest potential lies in the production of large systems.
The Art of Electronics
Paul Horowitz,Winfield Hill +1 more
TL;DR: The Art of Electronics as mentioned in this paper is widely accepted as the best single authoritative book on electronic circuit design and includes 90 oscilloscope screenshots illustrating the behavior of working circuits, dozens of graphs giving highly useful measured data of the sort that is often buried or omitted in datasheets but which you need when designing circuits, and 80 tables (listing some 1650 active components), enabling intelligent choice of circuit components by listing essential characteristics (both specified and measured) of available parts.
