8.2.1. Static CMOS Logic

Try these first

1. 1.

   What are the two types of transistors used in static CMOS logic?

   Hint

   Think about the letters in CMOS!

2. 2.

   Why is static CMOS logic described as 'static'?

   Hint

   Consider what happens when no signal changes occur.

3. 3.

   Which transistors are used in static CMOS logic?

   • Only PMOS
   • Only NMOS
   • Both PMOS and NMOS

   Hint

   Think about what CMOS stands for.

4. 4.

   True or False: Static CMOS logic requires a clock signal to maintain its logic state.

   • True
   • False

   Hint

   Consider the definition of static.

5. 5.

   Design a simple static CMOS NAND gate. Describe the arrangement of PMOS and NMOS transistors and explain how they function together.

   Hint

   Think about how the parallel and series arrangements interact with input states.

6. 6.

   Discuss the thermal implications of static CMOS circuits compared to dynamic circuits. Why is static CMOS preferred for higher densities?

   Hint

   Consider the power dynamics and their effects on heat generation.
