WebFigure 1 gives a Bode plot of an op-amp, which shows the relationship between the open-loop and closed-loop gains. The open-loop gain halves when frequency doubles. (On a logarithmic scale, it has a slope of -6 dB/oct or -20 dB/dec.) The closed-loop gain (G v) of the negative feedback circuit shown in Figure 2 is calculated as -R 2 /R 1. WebThe Inverting Operational Amplifier configuration is one of the simplest and most commonly used op-amp topologies. The inverting operational amplifier is basically a constant or fixed-gain amplifier producing a negative output voltage as its gain is always negative. We saw in the last tutorial that the Open Loop Gain, ( A VO ) of an operational ...
