Question

Figure P5.22 Figure P5.24 Vcc = 12V 5.23 In Problem 5.21, if only an A,--100 is needed, what are the changes in R and R2? Does the amplifier have any different 45k? output voltage swing? If so, what is it? c VBE =0.TV sin-10-200 (part(c), e-300 5.24 Analyze the circuit shown in Figure P5.24 to determine the following: lond in a. Icg, Av, and Rin b. Undistorted symmetrical output voltage swing 5.25 Analyze the circuit shown in Figure P5.25 to determine the following: Figure P5.25 a. Will the amplifier be conducting in the normal operating region? If so, what are Ico, A, and R.?

Explanation / Answer

5.23) there should be no change is R1 and R2. Amplifier will have the negative voltage cycle.

5.24) Icq = V/R = 12/55 = 0.21A

5.25) Amplifier will conduct in operationg region but in negetive waveform side so current would be reverse or negetive.

b) Amplifier would not be stable as it should get positive voltage continuesly.
