Tunnel Diode Operation, Characteristics, Working principle and Applications

Tunnel diode

A Tunnel diode is a p-n junction device which exhibits negative resistance i.e. when the voltage is increased the current through it decreased. It is also known as Esaki diodes named after Leo Esaki who received the Nobel Prize in 1973 for the discovery of electron tunnelling effect used in these diodes. In part of their operating range, these diodes have negative differential resistance¬† and therefore used in frequency converters, detectors, oscillators, amplifiers, switching circuits using hysteresis etc. In our previous article, we explain Photodiodes, Zener diode, Schottky Diode, LED etc. In this tutorial, we explain about Tunnel diodes operation, Read More …
