Chapter 6, Problem 6.12P

The parameters of the transistor in the circuit in Figure P6.12 are $\beta =150$ and $V_A=\infty$ . (a) Determine $R_1$ and $R_2$ to obtain a bias−stable circuit with the Q−point in the center of the load line. (b) Determine the small−signal voltage gain $A_{\upsilon }={\upsilon }_o/{\upsilon }_s$ .
