Summary

Description	English: Current-voltage (IV) diagram of a "linear" negative resistance, produced at the port of an amplifier with positive feedback. The curve has a straight line segment through the origin with negative slope -R, so applying a voltage v to the amplifier causes a proportional current i to flow out of the positive terminal, the opposite of an ordinary positive resistance. The device has both negative differential resistance (grey region) and negative static resistance (red region): $R={v \over i}={\Delta v \over \Delta i}<0\,$ Applying a large enough current of either polarity to it moves the amplifier into nonlinear regions of the curve, saturating the amplifier so the resistance becomes positive (black* portion of curve)*. This type of negative resistance is found in feedback oscillators, negative impedance converters, and active filters.
