Problem $2$: $30$ Points

Refer to the circuit in Figure $2.$

A$)20$ Pts Determine $V_{\text{o}\text{u}\text{t}}$ if $V_{in}=3\mathrm{.}5V.$

B$)10$ Pts: Determine the line regulation and load regulation for the circuit.

Assume $V_l=26mV,I_s={10}^{-16}A,$ and $n=1.$

Note: Stop iterations when successive circuit diode vollage approximations change by less than $\mathrm{.}01$V
