Basic Circuit and Analysis
INIC is a non-inverting amplifier (the op-amp and the voltage divider R1, R2 on the figure) with a resistor (R3) connected between its output and input. The op-amp output voltage is
The current going from the operational amplifier output through resistor toward the source is, and
So the input experiences an opposing current that is proportional to, and the circuit acts like a resistor with negative resistance
In general, elements, and need not be pure resistances (i.e., they may be capacitors, inductors, or impedance networks).

Famous quotes containing the words basic, circuit and/or analysis:
“Just as the constant increase of entropy is the basic law of the universe, so it is the basic law of life to be ever more highly structured and to struggle against entropy.”
—Václav Havel (b. 1936)
“each new victim treads unfalteringly
The never altered circuit of his fate,
Bringing twelve peers as witness
Both to his starry rise and starry fall.”
—Robert Graves (1895–1985)
“A commodity appears at first sight an extremely obvious, trivial thing. But its analysis brings out that it is a very strange thing, abounding in metaphysical subtleties and theological niceties.”
—Karl Marx (1818–1883)
