The open-loop gain of an electronic amplifier is the gain obtained when no overall feedback is used in the circuit. The open-loop gain of many electronic amplifiers is exceedingly high (by design) – an ideal operational amplifier (op-amp) has infinite open-loop gain. Typically an op-amp may have a maximal open-loop gain of around , or 100 dB.

Inverting Operational Amplifier - The Inverting Op-amp

WebThe open-loop transfer function a ( s) of this op-amp is plotted in Figure 12.22, where we see the low-frequency pole at 100 rad/s and high-frequency pole at 10 7 rad/s. This type of transfer function is typical of many commercially available op-amps. Sign in to download full-size image. FIGURE 12.22. WebIf the feedback loop around the system produces a loop-gain which is negative, the feedback is said to be negative or degenerative with the main effect of the negative feedback is in reducing the systems gain. If however the gain around the loop is positive, the system is said to have positive feedback or regenerative feedback.
