When I googled Miller integrator the sixth picture that popped up is this one, but I'm not completely sure what circuit it is and if it is something similar to the simple "standard" op-amp Miller integrator? How is it different? (and HOW different are the two? If that question makes sense. ) The picture leads to the circuit implemented in CircuitLab, and the simulations I have done indicate that it does some kind of integration.
This is not really my field, but the circuits are very important for my thesis in mathematics, and the circuit attached seems very interesting for what I'm working on (even more interesting than the normal op-amp integrator).
Is the circuit realistic? How does it behave, and why?
