The virtual ground concept is a technique used in electronics to create a reference point at a voltage level that is virtually equal to ground.

• The virtual ground concept is commonly used in operational amplifier circuits.

• It is achieved by using negative feedback to maintain the voltage at a specific node close to ground potential.

• This technique allows for easier analysis and design of circuits.

• For example, in an inverting amplifier circuit, the virtual ground is created at th...read more
