ECE212_Dynamic

The activity factor of NMOS dynamic gates

• is higher than that of static gates

• is equal to probability of output is HIGH

• is equal to probability of output is LOW

• is equal to probability of output is HIGH multiplied by probability output is LOW

The output of an NMOS dynamic gate is floating

• in precharge phase

• in evaluation phase and output is one

• in evaluation phase and output is zero

Dynamic gates

• can work at any frequency

• have a minimum frequency to work at

• have a maximum frequency to work at

The following statements are not correct

• dynamic gates are faster than static gates

• dynamic gates are slower than static gates

• power consumption of dynamic gates is higher than that of static gates

• power consumption of dynamic gates is lower than that of static gates

The logical effort of a 2-input NMOS dynamic NOR gate is equal to

• 1

• 2

• 2/3

• 5/3
