Question 27
Calculate the minimum power rating ($P_Q$) for transistor in the loaded Common Emitter Amplifier below:
Assume $\beta_{DC} = \beta_{AC} = 149$, Use the exact method to calculate $I_E$.
$V_{CC} = 12\ V$, $R_1 = 680\ \Omega$, $R_2 = 510\ \Omega$,
$R_C = 85\ \Omega$, $R_{E1} = 4.7\ \Omega$, $R_{E2} = 75\ \Omega$, $R_L = 100\ \Omega$
