# Electronics/Op-Amps/Non Linear Configurations/Negative Impedance Converter

## Configuration[edit]

## Operation[edit]

Creates a resistor having a negative value for any signal generator

- In this case, the ratio between the input voltage and the input current (thus the input resistance) is given by:

In general, the components , , and need not be resistors; they can be any component that can be described with an impedance.
