Explanation: For better resolution of output, the input binary word length has to be increased. As the number of bit increases, the range of resistance value increases. 8. The smallest resistor in a 12 bit weighted resistor DAC is 2.5kΩ, what will be the largest resistor value?
A. 40.96MΩ
B. 10.24MΩ
C. 61.44 MΩ
D. 18.43MΩ
Answer:A
Explanation: For better resolution of output, the input binary word length has to be increased. As the number of bit increases, the range of resistance value increases. 8. The smallest resistor in a 12 bit weighted resistor DAC is 2.5kΩ, what will be the largest resistor value?
A. 40.96MΩ B. 10.24MΩ C. 61.44 MΩ D. 18.43MΩ
Explanation: The largest resistor value for 12-bit DAC= 2n×R = 212×2.5kΩ = 4096×2.5kΩ =10.24MΩ. 9. CMOS inverter is used as SPDT switch in resistor DAC and is connected to the op-amp line. Find the output of CMOS, if the input applied is 1
