Circuit Board Layout Techniques

D.1. General Considerations

Prior discussions have focused on how to design op amp circuitry, how to use ICs, and the use of associated passive components. There is one additional circuit component that must be considered for the design to be a success—the printed circuit board (PCB) on which the circuit is to be located.

D.1.1. The Printed Circuit Board Is a Component of the Op Amp Design

Op amp circuitry is analog circuitry and is very different from digital circuitry. It must be partitioned in its own section of the board, using special layout techniques.
PCB effects become most apparent in radio frequency (RF) and high-speed analog circuits, but common mistakes described in this chapter can even affect ...
