Dear all

 

I want built a photodiode amplifier.Its bandwidth need over 100MHz to observe a pulse train.

 

I use photodiode wizard(PHOTODIODE | Analog Devices) and follow their suggestion.

 

But I test the circuit and there's a strange oscillation(as attachment) and exist when I block my photodiode.

 

How to solve this problem?
