Static and Dynamic Logic Gates Quiz

Which of the following is a characteristic of static logic gates?

• Require a clock signal to function

• Use only NMOS transistors

• Maintain output indefinitely without refresh

• Consume power even when idle

Dynamic logic gates operate in which two phases?

• Read and write

• Active and sleep

• Precharge and evaluate

• Setup and hold

A major disadvantage of dynamic logic gates is:

• High transistor count

• Slower speed than static logic

• Need for continuous refreshing and sensitivity to noise

• High static power consumption

Which logic style generally requires fewer transistors for implementation?

• Static CMOS

• Dynamic logic

• TTL logic

• BiCMOS logic

In static CMOS logic, what prevents short-circuit current in steady state?

• Pull-up resistor

• Only one of PMOS or NMOS is ON at a time

• High frequency clock

• Use of feedback loop
