EX $4$ Power Consumption

$1.$ Compute the switching power consumed by the multiplexer of Figure $6\mathrm{.}18,$ assuming that all significant capacitances have been lumped into the three capacitors shown in the figure, where $\backslash ($ C$=0\mathrm{.}3\backslash$mathrm$\{$pF$\}\backslash ).$ Also, assume that $\backslash ($ V$\_\{$D D$\}=2\mathrm{.}5\backslash$mathrm$\{$~V$\}\backslash )$ and independent, identicallydistributed uniform white noise inputs, with events occurring at a frequency of $100$ MHz Perform this calculation for the following:
