Hand Calculation: Since you now have the values of R1 and R2 resistors, obtain numeric value of voltage gain Av=Vo/Vi, and numerical values of input and output resistances Ri and Ro. Note that you need to DC analysis first. Do a hand calculation and calculate the DC collector current or IC. This is needed in order to calculate the small signal parameters gm and rπ and in turn to obtain the Av , Ri and Ro Hence, first perform a DC analysis (use the circuit in Figure 1 and take all capacitors open) and assume your transistor has a β=140.

Hand Calculation: Since you now have the values of R₁ and R₂resistors, obtain numeric value of voltage gain A_v=V_o/V_i, and numerical values of input and output resistances R_i and R_o. Note that you need to DC analysis first. Do a hand calculation and calculate the DC collector current or I_C. This is needed in order to calculate the small signal parameters g_m and r_π and in turn to obtain the A_v, R_i and R_o Hence, first perform a DC analysis (use the circuit in Figure 1 and take all capacitors open) and assume your transistor has a β=140.
