Question
Which of the following is an advantage of CMOS integrated circuits compared to TTL integrated circuits?
Answer Options
- A) Low power consumption
- B) High power handling capability
- C) Better suited for RF amplification
- D) Better suited for power supply regulation
Correct Answer: A
Explanation
CMOS (Complementary Metal-Oxide-Semiconductor) and TTL (Transistor-Transistor Logic) are two major families of digital integrated circuits. CMOS uses a pair of complementary MOSFETs in its design, which ensures that only one transistor is conducting at any given time during a steady state.
This design significantly reduces the current drawn by the chip when it is not actively switching states. The resulting advantage of CMOS integrated circuits is their remarkably low power consumption compared to older TTL technology, making them the standard for battery-powered or portable digital applications.
