Interesting. Need to learn with examples like if we have multiple switching regulators , fix voltage regulator, analog signals / supplies and digital signals on the same pcb. How to get rid of EMC problems? Explain with such an example as described above
Is there any type of filtering required for EMI/EMC. I have designed a microcontroller board , it has many other IC's. its working perfectly. but little problem of EMI/EMC. Is it possible for you to review my PCB ?
To calculate this, an interesting tool is Saturn PCB design toolkit. It's free: saturnpcb.com/?s=pcb+toolkit For 2mA, you will be fine with any trace width starting from the smallest one available in your PCB supplier's design rules.
