Chapter 9 - {PCB} Design Examples

Abstract

Publisher Summary This chapter explores various {PCB} design considerations using four design examples. The first example is a simple analog design using a single op-amp. The design shows how to set up multiple plane layers for positive and negative power supplies and ground. The second example is a mixed, digital/analog circuit. In addition to the tasks demonstrated in the first example, the design also demonstrates how to set up split planes to isolate analog and digital power supplies and grounds. The third example uses the same mixed, digital/analog circuit from the second example. It demonstrates how to use multiple-page schematics and off-page connectors to organize and simplify large circuit designs and to incorporate {PSpice} simulations into a {PCB} layer design. Finally, the fourth example is a high-speed digital design. It demonstrates how to design transmission lines, stitch muitilayer ground planes, perform pin/gate swapping, place moated ground areas for clock circuitry, and design a heat spreader.
