Open loop vs closed loop gain

Web9 de mai. de 2016 · Closing the loop on a open-loop system is a modification you make to your system just like any other modification. After that modification, you get a new system with a different transferr function that can be stable or unstable, independently of the previous system. Hope I was clear enough.

Web1 de dez. de 2014 · In the presented example, the closed-loop gain will be A cl = 1 + R 2 / R 1 However, we have to watch the stability properties of the circuit. For this purpose, it is common practice to investigate the loop gain (determination of stability margins). WebFor CFB amplifiers, the open-loop response is voltage out for a current in, so it is a transresistance (expressed in ohms) rather than a gain. This is generally referred to as a transimpedance, since there is an AC component as well as a DC term. The transimpedance of a CFB amp will usually be in the range of 500 kΩ to 1 MΩ.
