A collection of logic gates for which the static power dissipation is zero, and the dynamic power dissipation is 10 mW is operating at 50 MHz with a 5-V supply. By what fraction could the power dissipation be reduced if operation at 3.3 V were possible? If the frequency of operation is reduced by the same factor as the supply voltage (i.e., 3.3/5), what additional power can be saved?
