Question

The main advantage of CMOS over TTL circuit is its

• A. extremely low cost
• B. increased speed of operation
• C. much reduced power dissipation
• D. very small physical size

Hint:

CMOS = low power, TTL = higher power.

Answer 1

The Correct Option is C

Concept: CMOS technology uses complementary MOSFETs.

Step 1: Working principle Only one transistor conducts at a time.

Step 2: Power consumption Very low static power dissipation.

Step 3: TTL circuits Consume more power continuously.

Step 4: Advantage CMOS is highly efficient in power usage.

Step 5: Conclusion \[ \boxed{\text{Reduced power dissipation}} \]

Final Answer: \[ \boxed{(C)} \]
