1.2.2. CMOS Logic Gates

Try these first

1. 1.

   What does CMOS stand for?

   Hint

   Think about how CMOS is used in electronics.

2. 2.

   What type of logic does an inverter perform?

   Hint

   Consider what happens when the input is low.

3. 3.

   What type of gate is formed by connecting NMOS in series and PMOS in parallel?

   • Inverter
   • AND Gate
   • OR Gate

   Hint

   Recall the connections of NMOS and PMOS in these configurations.

4. 4.

   True or False: CMOS logic gates consume power during idle states.

   • True
   • False

   Hint

   Consider the operating states of CMOS technology.

5. 5.

   Design a complicated CMOS logic circuit using at least three different types of gates to achieve the function (A AND B) OR (C AND D).

   Hint

   Start by breaking down the Boolean expression into manageable parts.

6. 6.

   Explain, in detail, how the switching of inputs in a CMOS inverter affects power consumption.

   Hint

   Focus on the behavior of CMOS gates during static and dynamic states.
