| 4 | netlgc | inverter design ---- equal rise time and fall time By changing the W/L ratios. Wp(PMOS) = 2.5 to 3 times Wn(NMOS) |

| 5 | spacebac | inverter design ---- equal rise time and fall time If the inverter has the equal rise and fall time, then the charge and discharge current of the inverter's load capacator should be the same. So the aim is to choose the right W/L ratio of PMOS and NMOS, let the current of them to be equal. |
