Negative impedance converter


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:
R_{\text{in}} = -R_3 \frac{R_1}{R_2}

In general, the components R_1, R_2, and R_3 need not be resistors; they can be any component that can be described with an impedance.
