hi I'm reading a paper about a transimpedance amplifier. in the paper says The transimpedance gain transfer function and the bandwidth
can be calculated from the small signal model (the formulas are attached in the below pictures. i don't know how to get to the functions given below from small signal. i tried every way possible.can anyone help me ? is there a way i could get to these formulas by a program ?

yes for getting transimpedance function i tried a regular Nodal analysis and i got to different results.its really long and complicated i attached images of my analysis here and i think in this paper used a different simpler solution .

i figured out how to calculate transimpedance function but i cant get to the noise phrases by small signal. can anyone help me about noise phrases ?

Hello,

How difficult is it to have a better white balance (more contrast) in your pictures?
I just used GIMP to perform the white balance correction:

tia_DSC_0275_corr.JPG
I also rotated the pictures that needed it.
