TINA/Spice: Transimpedence amplifier for photodiode

Other Parts Discussed in Thread: TINA-TI

Tool/software: TINA-TI or Spice Models

Hello, 

I can't see the right output in my circuit. I know this circuit is unstable. but I design the resistence to have 4.8V in output when the current in input is 90uA and 0.1V in output when the current is 0uA. Where is the problem? I want also see the oscillation due the instability (figure 1) because there isn't a capacitor in feedback and also I want see the gain peaking (figure 2) in the frequency domain ( Transimpedence Gain , how can I measure it ? ).

Thank you
