Question $6)$ Consider a CMOS inverter circuit with the following parameters: Vdd $=5$V$,$ VTo,n $=0\mathrm{.}8$V $,$

VTop$=-0\mathrm{.}1$V$,$ unCox $=50$uA$/$v$,$ upCox $=20$uA$/$v$\text{'},$ lembda$=0,$ Both transistor have a channel length of Ln $=$ Lp $=1$um$.$ the total output load capacitance of this circuit is Cout $=2$pF$.$which is independent of transistor dimensions.

$$

Determine the channel width of the MOS and MOS transistors such that the switching

threshold voltage is equal to $2\mathrm{.}2$V and the output rise time is Trise $=5$ns$.$

ii$)$ Calculate the average propagation delay time Tp
