Non Inverting Op Amp Adder. As discussed earlier for the non inverting amplifier there is always a 0 degree phase shift between input and output. The summing amplifier uses an inverting amplifier configuration i e.
The input signals to be added are applied to the non inverting input terminal of op amp. The second basic configuration of an operational amplifier circuit is that of a non inverting operational amplifier design. In this video the inverting and the non inverting summing amplifiers using op amp has been discussed along with the derivations.
The following figure shows the non inverting adder using op amp with two inputs v1 and v2.
If we want to achieve a negative result like v o v a v b then we have to use an inverting operational amplifier to design a summing amplifier. Therefore here we are getting a positive output. V v 0v the currents entering both terminals of the op amp are zero since the op amp is ideal. The following figure shows the non inverting adder using op amp with two inputs v1 and v2.
