General exam question G6B03
Subelement G6, CIRCUIT COMPONENTS· Group G6B
Which of the following is an advantage of CMOS integrated circuits compared to TTL integrated circuits?
- A.Low power consumption (correct answer)
- B.High power handling capability
- C.Better suited for RF amplification
- D.Better suited for power supply regulation
WhyAn advantage of CMOS integrated circuits over TTL integrated circuits is low power consumption. CMOS logic's complementary transistor pairs draw significant current only while switching states, so a CMOS chip consumes far less standing power than equivalent TTL logic, which is CMOS's main advantage, answer A. CMOS isn't known for high power handling, isn't especially suited to RF amplification, and isn't a typical choice for power supply regulation, so B, C, and D don't describe CMOS's real advantage over TTL.
