AC coupled transimpedance amplifier

[TravisAllen]

Hello,

I am trying to recreate this circuit in LTSpice: https://www.ti.com/lit/an/sboa324/sboa324.pdf?ts=1718157790252 but I am having not much luck. Find attached my current circuit layout.

I am fairly new to LTSpice so I am not sure if my command is correct or if I am putting in the correct signal.

Any and all help is greatly appreciated thanks!

OP power supply doesn't look right, you're applying 5V to V- pin and 0 to V+ pin.

Also what's the idea behind feeding sine to D1 anode?

The diode is emulating a photodiode that would be sourcing an offset AC signal. I removed the diode then just put into the system an AC signal with an offset. The goal is to try and remove that offset then amplify the AC signal. I switched the supply voltages which leaves me with this.
