Circuit Design Part B

Figure 2 shows that the Circuit A designed in Part A is cascaded with the Circuit B designed in Part A.
Since V_IB = V_OA, is V_OB = K_A×K_B×V_IA? The answer is ‘NO’! WHY?

Do the following parts.

1. Verify the answer ‘NO’ using a circuit simulator. Include your simulation results in your report.
2. Explain why the answer is ‘NO’. Provide detailed reasonings in your report using circuit theory, calculations, etc.

REDESIGN Circuit A and/or Circuit B to meet the following design requirements while satisfying the design constraints below.

Design Requirement

1. In the cascaded circuit, V_OA = K_A×V_IA. K_A is the same value given in Table 2 in Circuit Design Part A.
2. In the cascaded circuit, V_OB = K_B×V_IB. K_B is the same value given in Table 2 in Circuit Design Part A.
3. In the cascaded circuit, V_OB = K_A×K_B×V_IA.

Design Constraint

1. You are allowed to use resistors with resistances within the range of 100 Ω to 400 kΩ only. Refer to APPENDIX II for available resistors.
2. Use as FEWEST components as possible.
