Following are the benefits or advantages of Tunnel diode: Tunnel-Diode provides very high resistance to high nuclear radiations and magnetic fields. They are used in oscillator circuits, and in FM receivers. This is useful property as frequency converter. • Preferred semiconductors used in tunnel diode are Ge and GaAs. Since it shows a fast response, it is used as high frequency component. It has a low cost. This property of tunnel diode is very useful at microwaves for high speed applications. ➨The power output levels of tunnel diode are restricted to only few milliwatts because Longevity:Studies have been undert… Applications of Diode. tunnel diode, in the reverse direction, a large current flows which increases continuously as the voltage is increased, If a negative voltage of the magnitude of point 4 in Figure 1.2 were applied to a tunnel diode, the resulting current would be many hundreds of times higher then when this voltage is applied in the positive direction. It works on the principle of the Tunneling effect. It was the quantum mechanical effect which is known as tunneling. The charge carriers can easily cross the junction as the width of the depletion layer has reduced up to a large extent. It is one type of twisted pair cable. Advantages & Disadvantages of Tunnel Diode The tunnel diode has low cost. Understanding is Power.… At a tunnel diode, considering its advantages and disadvantages to discover whether it is. Advantages of Tunnel Diode: It is one of the useful diodes; these diodes have robust nature. The tunnel diode is made by doping the semiconductor material ( Germanium or gallium arsenide) with a large number of impurities. The tunnel diode is also known as Esaki diode is a type of diode that has a large value of negative resistance. Also the resistance is less for little forward voltage. Once the voltage rises high enough suddenly the current again st… • Doping levels at p-side and n-side are very high. Benefits or advantages of Tunnel diode Following are the benefits or advantages of Tunnel diode: ➨Current due to majority carriers in tunnel diode responds much faster to voltage changes. ➨It is used to suppress voltage spikes. Diodes are mainly used in rectifiers, clippers, clampers, snubber circuits and voltage regulators. Disadvantages: 1. low tunneling current thus it’s classified as a low power component (not good parameter in case of oscillators), 2. high manufacturing costs, 3. no isolation between input and output. A diode is a two-terminal unidirectional power electronics device. Diode logic (DL), or diode-resistor logic (DRL), is the construction of Boolean logic gates from diodes.Diode logic was used extensively in the construction of early computers, where semiconductor diodes could replace bulky and costly active vacuum tube elements. between conduction band and valence band. It is sometimes known as Esaki Diode named after Leo Esaki. Thus, charge carriers do not need any kinetic energy to move across the junction; they simply punch through the junction. difference between OFDM and OFDMA A tunnel diode or Esaki diode is a type of semiconductor diode that has effectively " negative resistance " due to the quantum mechanical effect called tunneling. ➨It exhibits negative resistance characteristic as shown in the figure, Tunnel Diode. It was invented in August 1957 by Leo Esaki, Yuriko Kurose, and Takashi Suzuki when they were working at Tokyo Tsushin Kogyo, now known as Sony.
