Open loop vs closed loop gain

Web14 de nov. de 2010 · To obtain closed loop gain (transimpedance gain) you should use AC analysis: set AC mag of input current source to 1, run AC analysis, AC value of the output voltage is the transimpedance gain. BillQ said: Moreover, the transimpedance amplifier should have a gain with a unit of Ohm (V/A), this can't be converted into dB. 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.
