$($a$)(1$ pt$)$ Determine A$,$ B$,$ and C to maximize the clock frequency if the circuit has positive clock skew and find that clock frequency. Assume all the D$-$FF setup, hold and c to q times are all zero. Now assume $$A $=0\mathrm{.}2$ns$,$B $=0\mathrm{.}1$ns$,$ and $$C $=0\mathrm{.}3$ns and the setup, hold, and tcq times are as given. $($b$)(1$ pt$)$ What is Tmin for Clk$2$ being fed from the right? $($c$)(1$ pt$)$ What is Tmin for Clk$1$ being fed from the left? $($d$)(1$ pt$)$ What is Tmin for both clocks if $$A $=$B $=$C $=0$ns$?($e$)(1$ pt$)$ If the clock has a worst$-$case jitter of $0\mathrm{.}05$ns$,$ how should the Tmin in $($b$)$ be adjusted?
