I have a signal oscillating at tens or hundreds of MHz (up to 200 MHz expected), with 2.5 V mean and approx 200 mV peak to peak. I'd like to produce a current proportional to this signal at approx 40-50 mA mean to drive a laser diode.
I'm thinking about using this kind of floating load voltage to current circuit:
Is this kind of circuit suitable for up to 200Mhz signal?
If yes, does the AD8000 opamp would be suitable?
If not, which kind of (simple) circuit should I use (I'm running single supply)?
Thank you very much for your help.
