What is Tunnel Diode A tunnel diode is a pn junction that exhibits negative resistance between two values of forwardvoltage (i.e., between peak-point voltage and valley-point voltage). A conventional diode exhibits *positive resistance when it is forward biased or reverse biased. However, if a semiconductor junction diode is heavily doped with impurities, it exhibits negative … Read more
