| Keywords: Active negative resistance - current controlled.svg 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 <font color red >red</font> region <br /> <math>R v \over i \Delta v \over \Delta i < 0 \ </math> 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 own Chetvorno 2013-07-22 Negative resistance Device current-voltage characteristics Cc-zero | ||||
