I design a circuit which is shown below,and it works
,but i don't know how to analyse it is kinda different with the basic differential circuits L1 is coil which is used to induce a changing magnetic field and i'd like to ampilify the induced current signal which is very small ,about 75mV(P to P).could you tell me how it works and how to calculate the amplifier's output.thank you very much
