17.13A particular inverter circuit initially designed in a 0.5-µm process is fabricated in a 0.13-µm process. Assuming that the capacitance C scales down in proportion to the minimum feature size (more on this in Section 17.4) and that the power supply is reduced from 5 V to 1.2 V, by what factor do you expect the dynamic power dissipation to decrease? Assume that the switching frequency f remains unchanged. 66.8
