10 Questions
What types of semiconductor regions are used in a bipolar transistor?
BJTs use two p–n junctions between two semiconductor types, n-type and p-type, which are regions in a single crystal of material.
How does a small current injected at one of its terminals control a much larger current flowing between the terminals in a bipolar transistor?
A small current injected at one of its terminals controls a much larger current flowing between the terminals through the process of amplification or switching.
Explain the difference between a bipolar junction transistor (BJT) and a unipolar transistor (FET).
A BJT uses both electrons and electron holes as charge carriers, while a unipolar transistor, such as a FET, uses only one kind of charge carrier.
What displaced the original point-contact transistor?
The superior predictability and performance of junction transistors quickly displaced the original point-contact transistor.
In what ways can the junctions in bipolar transistors be made?
The junctions in bipolar transistors can be made in several different ways, such as changing the doping of the semiconductor material as it is grown, by depositing metal pellets to form alloy junctions, or by such methods as diffusion of n-type and p-type doping substances into the crystal.
Who introduced the Karnaugh map method in 1953?
Maurice Karnaugh
What is another name for Veitch charts?
Marquand–Veitch diagrams or Svoboda charts
How are cells ordered in Karnaugh maps?
In Gray code
What is the main advantage of using Karnaugh maps?
Reduces the need for extensive calculations by taking advantage of humans' pattern-recognition capability
What do cells represent in Karnaugh maps?
Minterms and each cell value represents the corresponding output
