Question

A common-emitter amplifier is shown in the figure. The parameters of the transistors are given as follows: $eta_{DC1} = eta_{DC2} = 150$ $eta_{ac1} = eta_{ac2} = 100$ $V_{CC} = +10V$ $V_i = 1V_{rms}$ $C = 10mu F$ $R_1 = 33kOmega$ $R_2 = 22kOmega$ $R_E = 1.5kOmega$ Determine: (a) The DC bias point of the circuit. (b) The small-signal voltage gain $A_v = frac{V_o}{V_i}$.

          A common-emitter amplifier is shown in the figure. The parameters of the transistors are given as follows:
$eta_{DC1} = eta_{DC2} = 150$
$eta_{ac1} = eta_{ac2} = 100$
$V_{CC} = +10V$
$V_i = 1V_{rms}$
$C = 10mu F$
$R_1 = 33kOmega$
$R_2 = 22kOmega$
$R_E = 1.5kOmega$

Determine:
(a) The DC bias point of the circuit.
(b) The small-signal voltage gain $A_v = frac{V_o}{V_i}$.
