WebAs will be seen, the op amp is most prone to instability when it is configured as a unity-gain follower, either because (a) there is no attenuation in the loop, or (b) large common-mode swings, though not substantially affecting accuracy of the signal gain, can modulate the loop gain into unstable regions. WebOp-amp Parameter and Idealised Characteristic. Open Loop Gain, (Avo) Infinite – The main function of an operational amplifier is to amplify the input signal and the more open loop gain it has the better. Open-loop gain is the gain of the op-amp without positive or negative feedback and for such an amplifier the gain will be infinite but typical real values range …

WebAnother VGA configuration uses a DAC in the feedback loop of an op amp to adjust the gain under digital control, as shown in Figure 8 below. The digital code of the DAC controls its attenuation with respect to its reference input VREF, acting functionally similar to a potentiometer. Attenuating the feedback signal increases the closed-loop gain. Webop amp is in common usage, so this configuration is examined in detail, but the results are applicable to many other voltage feedback circuits.

WebFigure 2. Traditional Op Amp Circuit. For any given voltage at the output, if the open loop gain is infinite, the voltage difference between the two input pins (V DIFF) is zero and the op amp regulates to keep both of its input pins at the same voltage.Here, the output is fed back to the input via the resistive divider R1-R2, so the feedback fraction (β) is 0.1 (1k/10k).

WebThe issue there was to use an operational amplifier as attenuator (e.g., to convert an input voltage from 0..10 V to 0..2.5 V). As solution, a voltage divider to bring down the input voltage followed by a (unity-gain) buffer was suggested. This seems in line with what the book "Op Amps for Everyone" (by Carter, Mancini) suggests. Webwhere feedback network attenuation is high. As an example, the LM101 may be operated at unity gain in the inverting amplifier circuit with a 15 pF compensating capacitor, since the feedback network has an attenuation of 6 dB, while it requires 30 pF in the non-invertingunity gain connection where the feedback network has zero attenuation.
