Gain before feedback simualtion
WebThere is negative feedback around each op amp, and a global loop that includes one inverting and one non-inverting amp, so all loops have negative feedback. Notice that a local feedback signal flows clockwise through R4, while the global feedback through R4 flows counterclockwise. a. Circuit with breakpoints that kill both local feedback loops ... WebMay 17, 2015 · This is why you sometimes see opamp datasheets say the amp is "unity gain stable". That means it won't oscillate down to a gain of one. Among other things, such opamp can be safely used as a voltage follower. Internally compensating a opamp to be stable at unity gain lowers its gain*bandwidth product.

http://www.fox.ece.ufl.edu/Multiple-Loop_Feedback.html WebThis gain / bandwidth tradeoff is a powerful tool in the design of feedback amplifier circuits. Since the gain is now dominated by the feedback network, a useful relationship to consider is the sensitivity of this gain to variation in the op amp's natural (open-loop) gain. Before deriving the system sensitivity, however, it is useful to define ...

One is the "intrinsic" open loop gain which is extracted from the Vout=A (Vinp-Vinm) but the other is due to an attenuated signal which arises from the feedback resistor impedances and the amplifier input impedance.
