Low cost Low noise; Environmental immunity; Low power dissipation; Simplicity in fabrication Longevity; Disadvantages of tunnel diode: Low output voltage swing; Because it is a two terminal device, there is no isolation between input and output. The tunnel diode is made by doping the semiconductor material ( Germanium or gallium arsenide) with a large number of impurities. Die Tunneldiode, 1957 entdeckt vom japanischen Wissenschaftler Leo Esaki (deshalb auch Esaki-Diode genannt), ist ein Hochfrequenz-Halbleiterbauelement. They are used in oscillator circuits, and in FM receivers. The performance of the cellular system is highly affected by interference. Conversion of AC input voltage to the DC output voltage when AC voltage is applied to a diode is called as rectification. The voltage range, which can be operated properly in 1 volt or below. Advantages of Tunnel Diode. ➨It is a low noise device. Following are the benefits or advantages of Diode: ➨It functions as rectifier in order to convert alternating current into direct current. ➨It is used to suppress voltage spikes. Due to the creation of the tunneling effect used in tunnel diodes Esaki got the Nobel Prize in Physics. oscillators. ➨Large current flows at small value of reverse voltage due to considerable overlap The first class of intraband tunnel diodes are often called RTDs and the latter class of ITDs include the classic Esaki tunnel diode, also known simply as ITDs, and a hybrid device called a resonant interband tunnel diodes (RITDs). In the current I P known as peak current is corresponding to the voltage V P, the change in current to voltage (dI/dV) ratio stays 0. They are heavily doped and have very thin depletion zones in order to encourage quantum Advantages of Tunnel Diodes It is a low noise device. Advantages of Tunnel Diode: It is one of the useful diodes; these diodes have robust nature. • Preferred semiconductors used in tunnel diode are Ge and GaAs. Difference between TDD and FDD One of the main reason for the early success of the tunnel diode was its high speed of operation and the high frequencies it could handle.

It mentions Tunnel diode advantages or benefits and Tunnel diode disadvantages or drawbacks. It is sometimes known as Esaki Diode named after Leo Esaki. Being a two-terminal device, it provides no isolation between output and input circuits. Tunnel diodes are highly doped semiconductor devices and are used mainly for low voltage high frequency switching applications. Interference is the main problem in increasing capacity. It is one type of twisted pair cable. It is basically similar to the UTP. The tunnel diode was invented by Dr. Leo Esaki. The tunnel diodes are heavily doped p-n junction diodes with negative resistance over a portion in • They have very thin depletion zones ( 3 to 100 angstroms). It produces low noise, and their fabrication is also very simple. ➨It delivers low output voltage swing. Nevertheless it is still worth looking at a tunnel diode, considering its advantages and disadvantages to discover whether it is a viable option.
