Hi,

I'm trying to generate a pulse train that has the following parameters: 10uA for 50us, 0A for 50us, -10uA for 50 us, 0.4ms between each pulse. The problem is that the resistor over which the pulse needs to travel is on the receiving end of a wireless transfer circuit. I can get an initial signal on the transmitter side without difficulty, but I have no idea how to send it, intact, across several capacitors and inductors. The end application requires that no extra power source be used on the receiver end. I'm attaching what I have so far, along with the PSPICE stimulations(Input voltage and current across the load) CurrentAcrossLoad.PNGInputVoltage.PNG. If there is a better way to do this, I'm completely open to trying it (modifications on the receiving circuit are fine, I just can't use anything that requires a constant power source)!! Cir1.png

My electronics background is spotty, and I'd really appreciate advice on this! Thanks so much!
