A diode operates in forward bias and is described by Equation $10.4,$ with $V_{T}=$ $0.026 \mathrm{V},$ For $v_{D 1}=0.600 \mathrm{V}$, the current is $i_{D 1}=1 \mathrm{mA} .$ For $v_{D 2}=0.680 \mathrm{V}$, the current is $i_{D 2}=10 \mathrm{mA}$. Determine the values of $I$ and $n.$
We have a junction diode that has $i_{D}=$ $0.2 \mathrm{mA}$ for $v_{D}=0.6 \mathrm{V}$. Assume that $n=2$ and $V_{T}=0.026 \mathrm{V} .$ Use the Shockley equa. tion to compute the diode current at $v_{D}=$ $0.65 \mathrm{V}$ and at $v_{D}=0.70 \mathrm{V}.$
Design an abrupt $\mathrm{Si} p^{+}-n$ junction diode that has a reverse breakdown voltage of $130 \mathrm{~V}$ and a forward-bias current of $2.2 \mathrm{~mA}$ at $V_{e}=0.7$ volt. Assume $\tau_{m}=10^{-7} \mathrm{~s}$.
