WebHari, You are right, the virtual ground is a concept, mental construct. The virtual ground only exists when the output is in the normal range, not at VOL and VOH level. Once the op amp output gets to maximum low or high level, the gain of the op amp drops to zero. The virtual ground only works if op amp gain is much greater than circuit ... WebThis condition is met when a negative-feedback circuit is formed using a differential amplifier with a high open-loop gain. When the input terminal on one side is grounded to …

In the theory of electrical networks, a virtual ground (or virtual earth) is a node of the circuit that is maintained at a steady reference potential, without being connected directly to the reference potential. In some cases the reference potential is considered to be that of the surface of the earth, and the reference node ...
