Where can i find the circuit to drive the antenna at 125khz? (I have a antenna 1.6uH)

What chips need to use in this circuit?

I want to detect the Proximity card within 10cm.

Can anyone help me,Thanks!!

I guess it's for RFID, at 125kHz. On the Microchip website you can find some design examples:

or search RFID on microchip.com

Actually, I want to make a card reader to read the EM RFID CARD at 125kHz. And I found the Philips IC HTRC11001T, but I don't know how to use its.

You can use also the U2270B from Atmel: cheap and reliable.

htrc11001t circuit design

u can also visit d site's download section-- h**p://rfid-handbook.de

it has documents containing formulae about antenna design etc 4 rfid and also an open source executable file which will help u calculating d parameters 4 different carrier frequencies like 13.56mhz etc
