Tunnel Diode: As said above, Tunnel Diode also known as Esaki diode, after its inventor, is probably the best-known device that exhibits negative resistance. The tunnel diode is a type of ...

And that’s where the tunnel diode comes in. Tunnel diodes have a negative-resistance region that can be used to amplify and oscillate at extremely high frequencies in extremely simple circuits ...

The tunnel diodes we mentioned above are probably the best known devices that exhibit negative resistance, and there was a time in the early 1960s before transistors gained extra performance that ...

Plastic Diode Could Lead To Flexible, Low Power Computer Circuits, Memory Date: November 15, 2005 Source: Ohio State University Summary: Researchers have invented a new organic polymer tunnel ...

The diodes work at room temperature on just 1.5 Vdc and consume little power. The group concedes plastic probably won't replace silicon entirely.

Fig 1. The curve tracer circuit is a simple transimpedance amplifier that converts the device test's IDS into an output voltage. Figure 2 is an oscillo scope screenshot of a transfer curve being ...
