    Hello I'm working on a project in which one I've created a rfid tag reader but the tag I've found doesn't work I think so I was trying to test it on LTspice IV but I don't know where I'm failling.

    I have to do this :[​IMG]

    The two generator on the left are supposed to make some square wave signal 0-5V, and the little circuit on the left represents the RFID TAG. I've managed to do this :[​IMG]

    But the running simulation is completely different, the sin signal is not even changed by the induction.

    Sorry for my poor english, and thanks to anyone who will be able to help me

    I don't understand the circuit difference between your two sims. What are the signals generated by V1, V2 and V3? What is a "running simulation"?
