I'm in favor of the star topology earth where all the circuits should be around the principal ground input or the regulators. An analog or sensitive circuit can not be placed in power circuit's way. | |
| Jul 4, 2013 at 22:45 | comment | added | arnuschky | OK thanks, I will fix the power plane. I am not sure if I should join the PGND and AGND. Don't I run the risk of seeing the currents from the SMPS in the analog circuits? Regarding the output caps: According to you, I should move them to GND? This is the opposite from what AndyAka said in the other question. | |
| Jul 4, 2013 at 13:52 | comment | added | Jesus Castane | @arnuschky I don't agree with the separated GNDs. It sometimes create more problems that it solves. In some way the output capacitors of your SMPS are the power supply of your circuit. So let's consider C17 and C18 your power supply. Their Vcc pins powers all your circuit BUT their GND point is isolated (Ok. not isolated but too far) from your circuit! In my opinion this is a really big problem. Why do you don't consider join PGND and AGND? Attention with your feedback track. It cross a GND split! Keep it over the same power plane. | |
