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

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.
