Summary
| Description |
English: Current-voltage (IV) curve of a negative differential resistance device, showing how it can amplify an AC signal applied to it. The diagram shows a negative diff. resistance device biased into its negative resistance region with a DC bias voltage Vbias, and an AC voltage Δv applied to it, showing the current and voltage waveforms across it. In the negative resistance region an increase in voltage will cause a decrease in current, so Δi and Δv have opposite signs. Therefore the AC current and voltage waveforms across the device are 180° out of phase (indicated by the colored half-cycles). So the AC power dissipation in the device, the product of the AC voltage and current PAC = ΔiΔv is negative, it produces power that is consumed by the external circuit. Therefore with the proper external circuit it can increase the power of an applied signal, amplifying it. |
