Dear TI community,
I use the following circuit - see below- and I have difficulty in understanding and calculating transfer function of this schematics.
Output voltage seems to be equal to input voltage reference injected and TINA AC transfer function gives me a unity gain at low frequencies.
When I try to calculate it by theory, I must have a mistake since I find a pure integrator and a pole which is not what TINA AC transfer function gives me.
Anyone could help me in understanding this schematics please ?
