Single ended to differential in transimpedance amplifier

[timedate]

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...

Why not use a balun?

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.
