R Figure 1 A 4-bit Reduced-Resistance-Ratio D/A Converter (a) Calculate the output voltage Vout of the 4-bit converter. (10 %) (b) Decide the feedback resistor value of the 4-bit converter if the maximum output voltage Vout = Vref - VLSB. (10 %) You are asked to design a 6-bit Reduced-Resistance-Ratio D/A Converter based on the D/A shown in Figure 1 for a new electronic system. (C) Draw a diagram to show the 6-bit Reduced-Resistance-Ratio D/A Converter with proper resistor values. (10 %) (d) Calculate the 6-bit D/A converter output voltage. (10 %) (e) Discuss if a 5-bit D/A converter using Reduced-Resistance- Ratio D/A structure can be designed. What would be the better structure which can be used to design a 5-bit D/A converter among Binary Scaled D/A converters? (10 %)
