I think so too -- but it may depend on what we build. Indeed I have seen recommendations to employ inductors in newsgroup sci.electronics.design. I use an analog ground where my OpAmps reside, and a digital ground for FPGA, uC. Situation is more complicated for DC/DC-converters or ADC, there are detailed shapes for ground and power planes in some datasheets. But my question currently is not how it should look, but how I build it best with pcb. > > How do I best divide a copper area (physically) into subsections with > > complicated shape/outline. > > Is there a good way to do this with PCB?
