Step 1 of 4 8.012E Consider the expression for the output resistance of the CG amplifier at (1) Substitute 0 for R, = Therefore, the value of the input resistance at = is ro Step 2 of 4 Recall equation (1). Substitute for As it implies = Therefore, the value of the input resistance at R, = is Step 3 of 4 Recall equation (1). Substitute for R, As it implies Therefore, the value of the input resistance at = is Step 4 of 4 Recall equation (1). Substitute 8 for R, As it implies Therefore, the value of the input resistance at R, = 8 is 8
