I am designing an RFID reader(125Khz). The series resonance circuit is fit to transmit and parallel resonance circuit is good for receive. If I want to use one coil in the reader, how to choose ? The coil current is about 150-200mA, which will make enough energe to transponder. Any suggestions and ideas are helpful.

Thanks!
