FET Flashcards
(6 cards)
1
Q
What does FET stand for?
A
Field effect transistor
2
Q
What is the main difference between BJT and a FET?
A
BJT is current controlled while a FET is voltage controlled
3
Q
What is another difference between BJT and FET
A
FET is unipolar and only deals with one charge carrier whether it be holes or electrons
By BGT functions with both charge carriers
4
Q
What is one of the most important characteristics of an FET?
A
It’s high input impedance
5
Q
What are the two types of FETs?
A
JFET which stands for junction field effect transistor
And MOSFET, which stands for metal oxide, semiconductor field effects transistor
6
Q
What is JFET?
A
A type of transistor that can use current using an electric field
