1.6.2. Power Consumption in High-Density Designs

Try these first

1. 1.

   What is dynamic power consumption?

   Hint

   Think about when a circuit is changing its output.

2. 2.

   Define static power consumption.

   Hint

   Relate this to how CMOS devices operate in low-power mode.

3. 3.

   What is the primary characteristic of dynamic power consumption?

   • It is constant
   • It increases with switching frequency
   • It is the same as static power

   Hint

   Think about how often the transistors are changing states.

4. 4.

   True or False: Static power consumption is higher than dynamic power consumption in high-density designs.

   • True
   • False

   Hint

   Compare the operational states of both types of power.

5. 5.

   Detail a situation where managing thermal effects in a high-density circuit becomes critical, and propose a solution.

   Hint

   Consider devices that experience significant processing loads.

6. 6.

   Calculate the dynamic power consumption of a circuit operating with capacitance of 5 nF, at a supply voltage of 1.2 V, and a switching frequency of 1 GHz.

   Hint

   Apply the power consumption formula while carefully converting unit measurements.
