What does it means by common mode for a non differential circuit?
for differential circuit, it has two inputs, +, - inputs. Common mode refers to something that common to both inputs.
But for non differential circuit, it doesn't not have two inputs and still it use the term common mode.
like the diagram listed. Common mode means what? Here, Vcm is common mode voltage.
So what the are two voltages it trying to compare.
