Hi, all

Does anybody know how to play a single ended to differential conversion in the transimpedance amplifier ?

Just like the red circle in the Figure.



My input analog signal is 50MHz, amplitude is about very low, about 1mV.

So, should I use a balun or fully differential amplifier like the following circuit？

 

I have seen the same post two days ago. Did you delete the old thread and started it anew? The first image has been already uploaded on monday...
 

could you plz give me a hint how to delete a thread in edaboard, I searched but could not find it.

could balun deal with this very low input signal (small than 1mV) ?
 

Why it shouldn't? It depends on what you want. After balun you can amplifier your signal and so on.
