What does MOSFET stand for?
Metal–Oxide–Semiconductor Field-Effect Transistor
What is a MOSFET mainly used for?
Switching and amplifying electronic signals.
What are the three main terminals of a MOSFET?
Gate, drain, source
Which MOSFET terminal controls the flow of current?
Gate
Does a MOSFET use current or voltage to control it?
Voltage
What does BJT stand for?
Bipolar Junction Transistor.
What is one main difference between a MOSFET and a BJT?
MOSFET is voltage-controlled; BJT is current-controlled.
Which device usually uses less power: MOSFET or BJT?
MOSFET
What is an integrated circuit (IC)?
A chip that contains many electronic components on one piece of semiconductor.
Why were integrated circuits invented?
To make electronics smaller, faster, cheaper, and more reliable.
Around what decade were the first integrated circuits invented?
Late '50s
Who is credited with inventing the integrated circuit?
Thomas Adler and William Farnsworth
Jack Kilby and Robert Noyce
Henry J. Collins and Arthur Bellman
Edward Hoffman and Charles Whitaker
What problem did ICs solve compared to individual components?
Too many wires, large size, high cost, and low reliability.
How did ICs help advance computers?
They made computers smaller, faster, and more powerful.
Why were ICs considered revolutionary?
They allowed millions/billions of components on a single chip.
Name one device that uses MOSFETs and integrated circuits.
Smartphones, computers, cars, power supplies, TVs, etc.
