*Question G6B03:
Which of the following is an advantage of CMOS integrated circuits compared to TTL integrated circuits?*  

*Correct Answer is  A: Low power consumption*  

### AI Response: (may contain errors)  

The correct answer to the question is **A: Low power consumption**. 

### Explanation of the Correct Answer:
- **Low Power Consumption**: CMOS (Complementary Metal-Oxide-Semiconductor) technology is known for its low power usage. This is because CMOS circuits only draw significant power during the switching of states (from 0 to 1 or 1 to 0). When in a stable state, they consume very little power, making them ideal for battery-operated devices and applications where energy efficiency is crucial.

### Explanation of the Incorrect Choices:
- **B: High power handling capability**: 
  - TTL (Transistor-Transistor Logic) circuits can handle higher power levels compared to CMOS. TTL is generally more robust in terms of power output, making it suitable for applications requiring higher drive capabilities.

- **C: Better suited for RF amplification**: 
  - While both CMOS and TTL can be used in RF applications, CMOS is not inherently better suited for RF amplification. RF amplification often requires specific design considerations that are not exclusive to either technology. In many cases, bipolar junction transistors (BJTs), which are used in TTL, are preferred for RF applications due to their higher gain and frequency response.

- **D: Better suited for power supply regulation**: 
  - Power supply regulation typically involves linear regulators or switching regulators, which can be implemented using various technologies, including both CMOS and TTL. However, CMOS is not specifically better suited for this purpose compared to other technologies. 

### Summary:
- CMOS is favored for its low power consumption, making it ideal for energy-sensitive applications.
- TTL is better for high power handling and certain applications like RF amplification and power regulation.

This understanding of the advantages and limitations of CMOS versus TTL will help you in the Extra Class exam and in practical applications of these technologies.
