4. You are required to design a BJT amplifier. Either Circuit A or B as shown in Figure 4,
give some justification on your design configuration selection.
Given that Vcc= 16 V and Icq = 2 mA. The intended Q-point value should be located at the
centre on the DC load line ($V_{CEQ} = \frac{1}{2}V_{CC}$). The average $\beta$ for 2N2222 transistor will be
assumed to be 190. Let $V_E$ = 2V and $V_{RC}$ = 6 V, determine the resistor values that will
produce the intended Q-point.
