Negative Impedance Converter - Basic Circuit and Analysis

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 and/or circuit:

    Nothing and no one can destroy the Chinese people. They are relentless survivors. They are the oldest civilized people on earth. Their civilization passes through phases but its basic characteristics remain the same. They yield, they bend to the wind, but they never break.
    Pearl S. Buck (1892–1973)

    The Father and His angelic hierarchy
    That made the magnitude and glory there
    Stood in the circuit of a needle’s eye.
    William Butler Yeats (1865–1939)
