Chapter 33 Summary: Power Distribution DC Drop
Chapter 33 explains the tradeoffs associated with voltage drop: There is a desire to get almost zero DC voltage drop across ground planes, but because of the practical limits on copper plane thickness, this is not possible. As a result, PCB designs must be executed to get an acceptable drop with the copper available. The reader is provided a number of examples of DC drop calculations, and methods for determining resistance in rectangular planes and circular rings.
