In an Op amp, while finding the voltage gain, two situations can be considered, when no feedback loop is applied and when a feedback loop is in operation. When there is no feedback loop applied in the Op amp circuit, the voltage gain is termed as open loop voltage gain. Whe...
Op amps are very high gain devices. To achieve stable operation, op-amps are used with negative feedback. The gain of the device alone is called open loop gain, and the gain when configuring a negative feedback circuit is called closed loop gain. Closed-loop gain is not device-specific ...
Fig. 1 Bode plot of an op-amp Above the cutoff frequency where the gain drops -3dB below the passband, 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 g...

The open-loop gain (GV) of an op-amp has the same frequency characteristics as a first-order RC lowpass filter. At frequencies higher than the corner frequency (fC) at which the open-loop gain is 3 dB lower than the DC gain, the open-loop gain decreases
