The term negative resistance means negative differential resistance (NDR), . In general, a negative differential resistance is a two-terminal component which can amplify, [3] [11] converting DC power applied to its terminals to AC output power to amplify an AC signal applied to the same terminals. Zobacz więcej In electronics, negative resistance (NR) is a property of some electrical circuits and devices in which an increase in voltage across the device's terminals results in a decrease in electric current through it. This is in … Zobacz więcej In an electronic device, the differential resistance $${\displaystyle r_{\text{diff}}}$$, the static resistance $${\displaystyle R_{\text{static}}}$$, or both, can be negative, so there are three categories of devices (fig. 2–4 above, and table) which could be called … Zobacz więcej In a device or circuit with negative differential resistance (NDR), in some part of the I–V curve the current decreases as the voltage increases: Passive negative … Zobacz więcej The resistance between two terminals of an electrical device or circuit is determined by its current–voltage (I–V) curve (characteristic curve), giving the current $${\displaystyle i}$$ through it for any given voltage $${\displaystyle v}$$ across it. Most … Zobacz więcej Electronic components with negative differential resistance include these devices: • Zobacz więcej A point of some confusion is whether ordinary resistance ("static" or "absolute" resistance, $${\displaystyle R_{\text{static}}=v/i}$$) can be negative. In electronics, the term "resistance" is customarily applied only to passive materials and … Zobacz więcej In addition to the passive devices with intrinsic negative differential resistance above, circuits with amplifying devices like transistors or op amps can have negative resistance at their ports.
