Replace the MOS transistors in the amplifier in Fig. 7.45 with bipolar npn transistors. The emitter area

Question:

Replace the MOS transistors in the amplifier in Fig. 7.45 with bipolar npn transistors. The emitter area of Q₂is four times that of Q₁and corresponding bias currents are I_C1= 1 mA and I_C2= 4 mA. Repeat the calculations in Problem 7.33 using the following data. Data at the operating point: Q₁: Î² = 200, Ï„_F= 0.2 ns, C_Î¼= 0.2 pF, C_je= 1 pF, C_cs= 1 pF, r_b= 0, and r_o= ˆž.Q₂: Î² = 200, Ï„_F= 0.2 ns, C_Î¼= 0.8 pF, C_je= 4 pF, C_cs= 4 pF, r_b= 0, and r_o= ˆž.
