CFB feedback capacitor

Question asked by johnvood on Oct 28, 2016

Hello!
According MT-034, a CFB amplifier should not have a capacitor in the feedback loop. Is that mean, the capacitor shouldn't used alone, without resistor? If so, how minimum/maximum oscillation frequency could be calculated?
I'm trying to simulate following circuit in Multisim and Tina  and both have same successive result.

Another question is in signal inversion on negative input across the resistor.

Regards!
