Question:

The circuit in Figure 6.3 is biased at $V_{C C}=10 \mathrm{~V}$ and has a collector resistor of $R_{C}=4 \mathrm{k} \Omega$. The voltage $V_{B B}$ is adjusted such that $V_{C}=4 \mathrm{~V}$. The transistor has $\beta=100$. The signal voltage between the base and emitter is $v_{b e}=5 \sin \omega t(\mathrm{mV})$. Determine the total instantaneous values of $i_{B}(t)$, $i_{C}(t)$, and $v_{C}(t)$, and determine the small-signal voltage gain $A_{v}=$ $v_{c}(t) / v_{b e}(t)$.
