Hi,
I use an RFID reader for reading FDX tags. It utilizes ASK modulation so I designed a transformer power supply with LDO linear regulator but somewhere it doesn't work good and read range decreased. I think it's due to poor voltage quality because there are several motors , ... nearby. I utilized an EMI filter in series with P and N. but it still has a short read range.
anybody have a solution to this problem?
Thanks.
