4.1. Introduction

Try these first

1. 1.

   What does CMOS stand for?

   Hint

   Think about the type of technology we use for modern integrated circuits.

2. 2.

   What is the primary concern when designing low power circuits?

   Hint

   Consider the trade-offs that engineers must make.

3. 3.

   What is the role of advanced design strategies in low power circuits?

   • To increase performance without regard for power
   • To minimize power while maintaining performance
   • To scale down operating voltage only

   Hint

   Think about the balance required in electronic design.

4. 4.

   True or False: Static power consumption rises as device scaling decreases.

   • True
   • False

   Hint

   Reflect on the challenges of smaller devices.

5. 5.

   You are tasked with designing a low-power sensor for an IoT application. What strategies would you utilize, considering the constraints discussed?

   Hint

   Think about the type of application and its power requirements.

6. 6.

   Evaluate the effects of scaling on both dynamic and static power consumption in a modern CPU.

   Hint

   Consider the difference between active and idle states.
