    Hi,

    I making a RFID reader. I've already have a circuit in mind. But i'm having trouble simulating it in Pspice. How do you make a 125kHz squarewave input source? It input will be sent thru an RF choke. And i want to see the plot of the output. I need help with the squarewave.

    Use an oscillator. Get something like 1 MHz and divide it down. Use a FET to push the squarewave into the RF filter.
