I have a design involving 2 power supplies.
I made it using 4 layers.
I have components on top and bottom layers.
I used top layer for analog part.
I used layer 2 for both power supplies and signals because I get enough place to do so. I cannot use a smaller board.
I used layer 3 for signals.
I used bottom layer for digital part with MCU.
Is there any advantage to improve the design with 6 layers involving 2 planes, one both power supplies and the other one for GND.
Thanks for your thoughts.
