I found the problem with your AC analysis. At the time you are doing the frequency sweep, the transistor has no bias (is effectively turned off), so when you do the AC analysis, you are seeing the
open loop gain of the 741.
I re-ran my simulation of your circuit, but I specified that during the time I do the AC analysis, I first put 10mA into the current-to-voltage converter, and then let the AC analysis vary the current +-9.9mA centered on 10mA. This turns on the PNP transistor, and give a true picture of the frequency response. Note that in my attached sim,
the d.c. bias and
the a.c. amplitude are both specified independently (
10m and
AC 9.9m)
I am plotting the magnitude and phase of the
trans-impedance (gain) =V(out)/I(I1). Note that at frequencies below ~100kHz, the gain is correct 66 @ -180 degrees (-66 comes directly from R1), and then some funny stuff happens between 100kHz and 10Mhz. Note that I am using a much better opamp than a 741. To get rid of the peaking, I would put a 10nF capacitor in parallel with R1.
