Hi,All
I'd like to ask what is actually gnd reference for RFID Passive tag (such as 13.56MHz NFC) ?
because there is no connection to the PCB or any physical ground, how to define the ground for the reference of the internal circuits ?
Do the tags need a very solid reference ground for the internal circuit design ?
Thanks in advance
Regards,
Lisong
