How to make a reconfigurable circuit

  1. Aug 14, 2013 #1
    Hi,

    I had designed a rectifier with 4 stages. I want to design a re configurable circuit in such a way that I can use either 2-stage or 3-stage of the rectifier depending upon the output voltage.
    Output voltage depends on the distance between reader and tag. If both are near, then the output voltage is higher and sufficient to initialize the circuitary within the tag. So, at that instant, the output voltage at second stage is enough for me. In case, tag and reader are farther, I may need 3 stages of rectifier. Depending upon the output voltage at the second stage, I can have the flexibility to chose either second stage or the third stage. In such scenarios, please suggest me how to design a reconfigurable circuit for stage 2 and stage 3?

    What do you mean by "stages" in a rectifier? Are you using something like the Cockcroft-Walton multiplier?

    I have attached the circuit. Now, tell me what circuit can be added so that I can reconfigure the circuit either to 3-stage or 4-stage.
