VIRTUAL SHORT CONCEPT AND VIRTUAL GROUND CONCEPT OF OP-AMP - YouTube

WebA "virtual ground" is a wire in a circuit whose voltage is held to be zero not because it is directly connected to the true ground, but instead because it is actively driven to that voltage typically by feedback mechanisms. In the … 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 GND as shown in the figure, it is sometimes … WebThe reason why you get a virtual short with negative feedback is because negative feedback stabilizes the op amp in linear operation, and the output voltage can be described as GAIN*INPUT. Since the gain is very high, the input is very small. This is the condition of the virtual short. This is a general explanation, and is overlooking details ... cpm in or
