Hi,
I'm designing a battery recharger and I have some question about EMI effects. Should I put a ground layer under the inductor?
The switch is a PNP transistor. It has a dissipator connected in the collector. If I put the inductor near of the dissipator, could it work like a antenna (and it interferes on command circuit)?
I will use a two layer board and the circuit has a ground and an analogic ground. Should I make a ground plan and a analogic ground plan? or only a ground plan?
Does anybody have suggestions?
Regards,
Guilherme
