Hi all , Iam trying to simulate the Modified Greinacher voltage multiplier circuit( capacitor-diode series ) for RFID tags. This is being used for Livestock IDentification.
The specs are as follows: load current: 50uA input power : 600uW.@50ohm.
Iam using a matching network followed buy a two stage mulyiplier circuit.
Iam trying to calculate the input impedace of the voltage multiplier ciruit , so that I can design the matching network.
could you please let me know , what simulation techniques could be used to estimate the real and imaginary part of the input impedance.
I have tried injecting an AC current and measuing the voltage .But these give me wrong results.
Could you please let me know , how to set up the simulation , so that input impedance can be calculated after the circuit has reached steady state.
I would really appreciate any info regarding this.
thanks srinivasan.
