Disadvantage of Tunnel Diode
- No proper DC isolation.
- Smaller voltage swing.
- Can not be fabricated in large amount.
Tunnel Diode
The tunnel diode is also known as the “Esaki Diode”. It was invented by “Leo Esaki” in 1957, and for this invention, received the he received Nobel in 1973. It exhibits negative resistance, negative resistance means current decreases when voltage increases.
