Non Inverting Operational Amplifier Circuit. Non inverting operational amplifiers virtual short. The non inverting amplifier is the basic circuit obtained from amplifiers.
In the inverting amplifier the output is amplified and inverted phase of the input signal. The op amp non inverting amplifier circuit provides a high input impedance along with all the advantages gained from using an operational amplifier. This simply means that for an input signal with a positive phase the output will also be positive.
But in a non inverting amplifier the output is amplified and also the same as the input phase.
An amplifier that produces an amplified signal at the output having a similar phase as that of the applied input is known as the non inverting amplifier. In a non inverting amplifier there exists a virtual short between the two input terminals. This simply means that for an input signal with a positive phase the output will also be positive. Although the inverting amplifier is preferred in many cases it has two drawbacks.
