an op-amp in the real world is far from ideal. The output voltage range of an ideal op-amp is unlimited, but for a real opamp, it is limited by the DC supply connected to it. If the summing amplifier is powered by +15V and -15V, the output will be clamped before it reaches the...
As long as the op-amp gain is very large, the amplifier gain is determined by the external feedback resistor Rf and the input resistor Rin and not by op-amp parameters.If we apply KCL to the node at V- (the inverting input) and let the input current to the inverting input be I-,...

Can we add them all with one amplifier? Theoretically, yes. Practically, it is a different story. There is a practical limit on how many signals can be summed up with one amplifier. When the number of input signals grows, each signal component in the sum decreases in value. By the ...
I presented a method for designing a bipolar to unipolar converter using a summing amplifier. In this article I am going to show more examples of bipolar to unipolar converters which are based on a summing amplifier configuration. You can adapt them to your needs if you use the method I des...
