I am trying to simulate the frequency response of a trans-impedance amplifier in LTspice, with a current source input, as shown below:

enter image description hereenter image description here

My question is when doing ac analysis, the gain that LTspice plots, is it voltage gain (as in output voltage by the voltage at input node)? Or does it plot trans-impedance gain? (output voltage by input current) since my input is a current source. If it is the former, is there any way I can plot trans-impedance gain vs frequency in LTspice? enter image description hereenter image description here

What does Gain mean when LTSpice plots Gain vs Frequency in AC analysis?
