control system theory, loop gain is the sum of the gain, expressed as a ratio or in decibels, around a feedback loop. Feedback loops are widely used in electronics...

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...

} where AOL is the open-loop gain of the amplifier (the term "open-loop" refers to the absence of an external feedback loop from the output to the input)...

radiated power Gain before feedback Insertion gain Loop gain Open-loop gain Net gain Power gain Process gain Transmitter power output Graf, Rudolf F. (1999)...

Mathematically, positive feedback is defined as a positive loop gain around a closed loop of cause and effect. That is, positive feedback is in phase...

closed-loop transfer function of the system. The numerator is the forward (open-loop) gain from r to y, and the denominator is one plus the gain in going...

distortion is related to the extra loop gain used for startup. If there's a lot of extra loop gain at small amplitudes, then the gain must decrease more at higher...

together with a gain greater than one will result in a runaway situation. Both positive and negative feedback require a feedback loop to operate. However...

the gain to below the open-loop gain, the gain–bandwidth product of the closed-loop amplifier will be approximately equal to that of the open-loop amplifier...

the gain of the amplifier with feedback (the closed-loop gain), β is the feedback factor, and AOL is the gain without feedback (the open-loop gain). The...
