Op Amp question
Hi,
I'm trying to understand how the following circuit works.
View attachment 65175
I simulated it with the following results:

I don't manage to understand:
1. Why is it that when Vctrl = 467mV, then Vcap0=1.035V? (for Vset=0V).
2. What does the "Gain=100dB" (next to the OpAmp) mean?
I thought that differential OpAmp charges the output to either Vcc or Vee, no matter what the Gain is.
Thanks in advance.
