License Exam Quiz #277
de Steve, AE8AT

July 1789, a pivotal moment in the fall of the monarchy and establishment of a republic. You might think this day is also called Bastille Day in France, however, it is called Fête Nationale. The quiz topic this week is the field effect transistor (FET).


T6B08 What does the abbreviation FET stand for?
A. Frequency Emission Transmitter
B. Fast Electron Transistor
C. Free Electron Transmitter
D. Field Effect Transistor


G6A09 Which of the following describes MOSFET construction?
A. The gate is formed by a back-biased junction
B. The gate is separated from the channel by a thin insulating layer
C. The source is separated from the drain by a thin insulating layer
D. The source is formed by depositing metal on silicon


E6A09 What is a depletion-mode field-effect transistor (FET)?
A. An FET that exhibits a current flow between source and drain when no gate voltage is applied
B. An FET that has no current flow between source and drain when no gate voltage is applied
C. An FET that exhibits very high electron mobility due to a lack of holes in the N-type material
D. An FET for which holes are the majority carriers


Answers:
T6B08 = D
G6A09 = B
E6A09 = A
