4 results about "Open-loop gain" patented technology

The open-loop gain of an amplifier is the gain obtained when no overall feedback is used in the circuit. Open loop gain, in some amplifiers, can be exceedingly high. An ideal operational amplifier (op-amp) has infinite open-loop gain. Typically an op-amp may have a maximal open-loop gain of around 10⁵. The very high open-loop gain of the op-amp allows a wide range of feedback levels to be applied to achieve the desired performance.
