Question:

Consider the circuit in Figure P17.20. Assume transistor and diode parameters: $\beta=25, V_{\gamma}=V_{B E}($ on $)=0.7 \mathrm{~V}, V_{B E}($ sat $)=0.8 \mathrm{~V}$, and $V_{C E}($ sat $)=$ $0.1 \mathrm{~V}$. Determine $v_{1}, i_{1}, i_{B}, i_{C}$, and $v_{O}$ for

(a) $v_{I}=0$ and

(b) $v_{I}=3.3 \mathrm{~V}$.
