How is negative resistance created?

Due to Tunneling, when the value of forward voltage is low value of forward current generated will be high. It can operate in forward biased as well as in reverse biased. Due to high doping, it can operate in reverse biased. Due to the reduction in barrier potential, the value of reverse breakdown voltage also reduces. It reaches a value of zero. Due to this small reverse voltage leads to diode breakdown. Hence, this creates negative resistance region.

How to Calculate Magnitude of Negative Resistance?

Magnitude of Negative Resistance calculator uses Negative Resistance in Tunnel Diode = 1/(Negative Conductance Tunnel Diode) to calculate the Negative Resistance in Tunnel Diode, The Magnitude of Negative Resistance formula is defined as the effective opposition offered by the diode to the flow of current through it.
