ECE212_Dynamic2

An NMOS dynamic gate can be connected to a PMOS dynamic gate

• directly

• through an inverter

• through a PMOS dynamic gate

• through another NMOS dynamic gate

Charge sharing is less problematic when

• the internal cap is initially discharged

• the internal cap is initially charged

• the internal cap is large

• the internal cap is small

Dual rail domino gates

• have high dynamic power consumption

• are ratioed

• solve non-inverting logic problem

• don't need complimentary inputs

np CMOS

• requires differential clock

• has good NML and NMH

• implements non-inverting logic only

• are faster than normal domino

footless domino

• has lower logical effort than normal domino

• implements inverting logic

• reduces the clock load

• doesn't need the inverter between stages
