Question

Problem:

Design a CE amplifier to meet one of the sets of specifications below.  Assume R_I = 0 and R₃ = ∞ for your calculations and use standard resistor values.  Calculate the Q-point, A_v, R_in and R_out.  Simulate your design and compare with your calculations and with the specifications.  The simulations should include DC operating point, AC simulations of A_v, R_in and R_out, and a transient simulation demonstrating an undistorted output. We will define "undistorted" as THD ≤ 3%. Repeat the gain simulation with R_I = 100 W and R₃ = 100 kW and comment on the effect.

(i) A_v = 50 dB and R_in = 50 kW

(ii) A_v = 46 dB and R_in = 100 kW

(iii) A_v = 40 dB and R_in = 200 kW
