Problem $1[$Domino gate design$]$

$($a$)$ Explain how charge sharing can be prevented in domino CMOS.

$($b$)$ Design a domino gate implementing the function $f_1=Ao+B.$

$($c$)$ A possible modification of domino logic is to have multiple outputs from a single gate. Modify the domino gate of part $($b$)$ above to implement two additional functions $f_2=Ao+Bo+C,$ and $f_3=Ao+Bo+Co+D.$ Assume that complemented inputs are available and they do not come from dynamic gates.

$($d$)$ The practicality of this approach for designing multiple$-$output domino gates is a matter of debate. Comment on the advantages and disadvantages of this approach.
