Hi! 

 

Iam trying to built a 100 MHz Free-Space Optic Receiver. i use OPF430 from Optek Inc. as photodetector and AD8015 as my TIA.

The photodiode has 2pf capacitance and 2 ns rise time (according to datasheet). But i still can not get the output i desired. 

So, is it possible to get the differential output as i desired from my schematic?

 

i attached the schematic for explain my problems.
