In a $\backslash (\backslash$mathrm$\{$p$\}^\{+\}\backslash$mathrm$\{$n$\}\backslash )$ diode reverse biased at $5$ V $,$ the generated capacitance is $20$ pF $.$ If the doping of the p side is doubled and the bias is change to $20$ V $,$ what will be the change in capacitance? If now the bias is changed to $100$ V $,$ then what will be the change? $\backslash ($ P $\backslash$mid $63\backslash )$
