Analog front end designing

[abcs]

Hi,
I have to tap OFDM modulated signal from an IC.
Then from the constant AC source waveform I want to get that OFDM modulated waveform as output from combination analog devices like filters mosfets gain amplifiers etc. Input being a constant current source.
Basically I need to design Analog front end for interfacing that IC to the Constant current regulator system.
Can any one help me out with this?

I really have no idea what you are trying to do. :?: What does OFDM have to do with a Constant current regulator?

Post a block diagram of what you are attempting.
