Question:

For the circuit in Figure P6.15, the transistor parameters are $\beta=100$ and $V_{A}=\infty$. Design the circuit such that $I_{C Q}=0.25 \mathrm{~mA}$ and $V_{C E Q}=3 \mathrm{~V}$. Find the small-signal voltage gain $A_{v}=v_{o} / v_{s}$. Find the input resistance seen by the signal source $v_{s}$.
