Transistors
What is a transistor and what are its three main terminals?
A transistor is a semiconductor device used to amplify or switch electronic signals. Its three main terminals are emitter, base, and collector.
What are the three main terminals of a MOSFET?
Gate, drain, source
What is a System on a Chip?
A System on a Chip is an integrated circuit that combines multiple system components on a single chip.
Complete the sentence: A car is ___ than a bike.
FASTER
She is a very ___ person. (CREATE)
Creative
What is the difference between an NPN and a PNP transistor?
In an NPN transistor, current flows when the base is positive relative to the emitter. In a PNP transistor, current flows when the base is negative relative to the emitter.
Why are MOSFETs widely used in modern integrated circuits?
Because they consume low power, have high input impedance, and can be easily miniaturized.
Name some components typically found in a SoC.
CPU, GPU, memory controllers, I/O interfaces, and sometimes AI accelerators.
What are the comparative and superlative forms of “good”?
Comparative: better — Superlative: the best
His explanation was completely ___. (CONFUSE)
Confusing
How does a transistor amplify a signal?
A small input signal controls a larger current, making the signal stronger.
What is an integrated circuit (IC)?
A chip that contains many electronic components on one piece of semiconductor.
What is the difference between a microcontroller and a SoC?
A microcontroller is designed for specific control tasks, while a SoC integrates more complex components for general-purpose computing.
Choose the correct option:
This exercise is ___ than the previous one.
More difficult
The result was a success. → The experiment was ___.
Successful
What is the basic difference between a BJT and a MOSFET?
A BJT is current-controlled, while a MOSFET is voltage-controlled.
What does MOSFET stand for?
Metal–Oxide–Semiconductor Field-Effect Transistor
What are the advantages of using a SoC?
Reduced power consumption, smaller size, higher performance, and lower cost.
Write a sentence using the superlative form of “interesting”.
This is the most interesting book I have ever read.
There has been a significant ___ in prices. (INCREASE)
Increase
How does temperature affect transistor operation?
An increase in temperature can increase leakage current and reduce stability, potentially causing thermal runaway.
What problem did ICs solve compared to individual components?
Too many wires, large size, high cost, and low reliability.
What role does a SoC play in a smartphone?
It manages processing, graphics, connectivity, and power efficiency in a single integrated unit.
What is the difference between “better than” and “the best”?
“Better than” compares two things, while “the best” compares one thing with all others in a group.
Use the word “ABLE” to form a different part of speech and write a sentence.
Ability — She has the ability to solve complex problems.
