Tunnel diodes and Gunn diodes are examples of components that have negative resistance. Hysteresis vs single-valued: Devices which have hysteresis; that is, in which the current–voltage relation depends not only on the present applied input but also on the past history of inputs, have I–V curves consisting of families of closed loops. Each ...
When more accuracy is desired in modelling the diode's turn-on characteristic, the model can be enhanced by doubling-up the standard PWL-model. This model uses two piecewise-linear diodes in parallel, as a way to model a single diode more accurately. PWL Diode model with 2 branches. The top branch has a lower forward-voltage and a higher ...
English: Diode I-V diagram. Includes three main areas of operation: breakdown, reverse-biased, and forward-biased. Vbr denotes the breakdown voltage, and Vd denotes the voltage that is typically considered "on" (conducting current).

Shockley derives an equation for the voltage across a p-n junction in a long article published in 1949. [2] Later he gives a corresponding equation for current as a function of voltage under additional assumptions, which is the equation we call the Shockley ideal diode equation. [3]
Laura-Jane Seaman, 36, was breastfeeding in her hospital bed with plans to go home following the “uneventful” vaginal birth of her baby at Broomfield Hospital, in Essex, U.K., on Dec. 21, 2022 ...
Stoli. Stoli Group USA, the owner of the namesake vodka, filed for bankruptcy in December. A number of things went wrong for the unit, including a slowing demand for spirits, a major cyberattack ...
English: I–V curves (current–voltage characteristics) for four devices: A resistor with large resistance, a resistor with small resistance, a diode, and a battery. An ideal battery would have a constant voltage (a vertical line in the I–V curve), but this one has an internal resistance that causes the I–V curve to tilt slightly away from vertical.
