The concept of negative resistance has always fascinated me. Of course, a true negative resistance is not possible, and what is meant is a negative differential resistance (NDR). But of course knowing ...

In electronics, negative resistance is an oddball property which occurs in a few nonlinear components. Just think that an increase in voltage across a device’s terminals results in a decrease in ...

Pulse-width-modulation (PWM) duty cycles above 50% require a compensating ramp — called slope-compensation — to avoid instability. With traditional slope-compensation solutions, it is difficult for ...

With silicon fast running out of steam and no clear path beyond 14nm, graphene might just be the light at the end of the tunnel. For that to occur, though, we first need to turn graphene into a ...

In the presence of a magnetic field, negative resistivity can produce a positive resistance, along with a sign reversal in the Hall effect, in GaAs/AlGaAs semiconductor devices. In a paper appearing ...

In a paper appearing in Nature's Scientific Reports, Dr. Ramesh Mani, professor of physics and astronomy at Georgia State University, reports that, in the presence of a magnetic field, negative ...
