For reverse-bias potentials in excess of 10 V the capacitance levels off at about 1. Same basic appearance as Fig. The maximum level of I Rs will in turn determine the maximum permissible level of Vi. Sign Up Already have an access code? Be the first to like this. As the magnitude of the reverse-bias potential increases, the capacitance drops rapidly from a level of about 5 pF with no bias. Topics covered include:
The fact that the outermost shell with its 29th electron is incomplete subshell can contain 2 electrons and distant from the nucleus reveals that this electron is loosely bound to its parent atom. The application of an external electric field of the correct polarity can easily draw this loosely bound electron from its atomic structure for conduction.
Both intrinsic silicon and germanium have complete outer shells due to the sharing covalent bonding of electrons between atoms. Electrons that are part of a complete shell structure require increased levels of applied attractive forces to be removed from their parent atom.
Intrinsic material: That is, one with the fewest possible number of impurities. Negative temperature coefficient: Covalent bonding: An n-type semiconductor material has an excess of electrons for conduction established by doping an intrinsic material with donor atoms having more valence electrons than needed to establish the covalent bonding. The majority carrier is the electron while the minority carrier is the hole.
A p-type semiconductor material is formed by doping an intrinsic material with acceptor atoms having an insufficient number of electrons in the valence shell to complete the covalent bonding thereby creating a hole in the covalent structure. The majority carrier is the hole while the minority carrier is the electron.
A donor atom has five electrons in its outermost valence shell while an acceptor atom has only 3 electrons in the valence shell. Majority carriers are those carriers of a material that far exceed the number of any other carriers in the material. Minority carriers are those carriers of a material that are less in number than any other carrier of the material.
Same basic appearance as Fig. For forward bias, the positive potential is applied to the p-type material and the negative potential to the n-type material.
For most applications the silicon diode is the device of choice due to its higher temperature capability. Ge typically has a working limit of about 85 degrees centigrade while Si can be used at temperatures approaching degrees centigrade. Silicon diodes also have a higher current handling capability. Germanium diodes are the better device for some RF small signal applications, where the smaller threshold voltage may prove advantageous.
From 1. Usually, however, technology only permits a close replica of the desired characteristics. The most important difference between the characteristics of a diode and a simple switch is that the switch, being mechanical, is capable of conducting current in either direction while the diode only allows charge to flow through the element in one direction specifically the direction defined by the arrow of the symbol using conventional current flow.
From Fig. The transition capacitance is due to the depletion region acting like a dielectric in the reverse- bias region, while the diffusion capacitance is determined by the rate of charge injection into the region just outside the depletion boundaries of a forward-biased device.
Both capacitances are present in both the reverse- and forward-bias directions, but the transition capacitance is the dominant effect for reverse-biased diodes and the diffusion capacitance is the dominant effect for forward-biased conditions.
As the magnitude of the reverse-bias potential increases, the capacitance drops rapidly from a level of about 5 pF with no bias.
For reverse-bias potentials in excess of 10 V the capacitance levels off at about 1. Log scale: Using the bottom right graph of Fig.
For germanium it is a 6. For the high-efficiency red unit of Fig. Levels of part c are reasonably close but as expected due to level of applied voltage E. Both diodes forward-biased: The threshold voltage of 0. The result: Since all the system terminals are at 10 V the required difference of 0.
Positive half-cycle of vi: Positive pulse of vi: Negative pulse of vi: However, vo is connected directly through the 2.
For the positive region of vi: The right Si diode is reverse-biased. For the negative region of vi: The left Si diode is reverse-biased. Using the ideal diode Using the ideal diode approximation the vertical shift of part a would be V rather approximation would certainly be appropriate in this case.
Solution is network of Fig. Network of Fig. The maximum level of I Rs will in turn determine the maximum permissible level of Vi.
Z1 forward-biased at 0. A bipolar transistor utilizes holes and electrons in the injection or charge flow process, while unipolar devices utilize either electrons or holes, but not both, in the charge flow process.
