Problem $2$:

The switches operate as the following based on the non$-$overlapping binary phase clock. At the Phase $1$ of the clock, both S$1$ are turned$-$on $($the switch shorts the two ends$)$ and S$2$ is turned$-$off $($the switch opens the two ends$).$ At the Phase $2$ of the clock, both S$1$ are turned$-$off and S$2$ is turned$-$on$.$ Assume $V_{\text{R}\text{E}\text{F}}=0\mathrm{.}2[V],$ vin$=2[$V$],$

Q$1$: if $C1=C2=0\mathrm{.}01nF,$ how much is the output $(v_{\text{o}\text{u}\text{t}})$ after $1$ clock?

Q$2$: if $C1=0\mathrm{.}05nF$ and $C2=0\mathrm{.}01nF,$ how much is the output $(v_{\text{o}\text{u}\text{t}})$ after $1$ clock?

Problem $3$

The analog input range of a $4-$bit ADC is
