Chapter 6, Problem 6.23P

For the circuit in Figure P6.23, the transistor parameters are $\beta =80$ and $V_A=80\text{V}$ . (a) Determine $R_E$ such that $I_{EQ}=0.75\text{mA}$ . (b) Determine $R_C$ such that $V_{ECQ}=7\text{V}$ . (c) For $R_L=10\text{Ω}$ , determine the small−signal voltage gain $A_{\upsilon }={\upsilon }_o/{\upsilon }_s$ . (d) Determine the impedance seen by the signal source ${\upsilon }_s$ .
