Hi
I'm considering the TIA design with a feedback T network.
Target gain is around 120dB and BW shall be larger than 1MHz.
I've almost finished it and hope that you will take a review.
BW:
Stability:
And what I want to get rid of is the bias voltage for the T resistor.
But using a resistor devider will cause the unstability. (small resistor values will decrease the gain a lot)
So is there any other way to make it? I just want to avoi adding an opamp buffer here.
Thanks!
