Question

(a) In a Ge diode, the leakage current is $10\text{ }\mu\text{A}$ and the breakdown voltage is $25\text{V}$. Compute current for:

(i) Reverse bias of $24\text{ V}$

(ii) Reverse bias of $0.02\text{ v}$ and

(iii) Reverse bias of $0.3\text{ v}$.

Assume that $\eta = 1$ for Ge and $V_T = 26\text{ mv}$ at room temperature.

(b) Explain the zener diode as voltage regulator.
