Question:

Consider the Wilson current-source circuit shown in Figure 10.8. Assume the reference current is $0.25 \mathrm{~mA}$ and assume transistor parameters of $V_{B E}($ on $)=0.7 \mathrm{~V}, \beta=100$, and $V_{A}=100 \mathrm{~V}$.

(a) Determine the output resistance looking into the collector of $Q_{3}$.

(b) What is the change in $I_{O}$ as the output voltage changes by $+5 \mathrm{~V}$ ?
