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.
