Replace the NMOS transistors in Fig. 7.43 with npn transistors. The resulting ac schematics are of a common-emitter stage and a common-emitter€“common-base (cascode) stage. Repeat the calculations in Problem 7.29 using R_S= 5 kΩ, R_L= 3 kΩ, and the following data. Data: I_C= 1mA, β = 100, r_b= 0, C_cs= 1 pF, C_μ= 0.4 pF, f_T= 500 MHz (at I_C= 1 mA), and r_o= ˆž.
