電阻串式數位類比轉換器電路在實際應用上具有能迅速產生連續參考電壓值、保證單調性的好處，然而在實體佈局層面，如果導線電阻不一致時，會造成積分非線性誤差變差。利用我們所提出的局部性以及全面性佈局策略，依導線長度和接點個數來調整導線寬度，能有效率地同時降低探戈行軍式蛇行排法的導線電阻到8.99歐姆，並且控制導線電阻的標準差到0.055歐姆；外接引線時並且調整電阻兩端的接點個數，使電阻端點的阻值一致，如此來抑制非線性累積誤差達到0.3215個最小位元電壓以下。 The resistor-string digital-to-analog converter in actual application can be used to generate continuous-reference voltage output quickly and the monotonicity is guaranteed. The unbalanced wire resistance in the physical layout implementation will make the Integral Nonlinearity error greater. Using our Local and Global strategies and base on interconnect length and contact count to adjust interconnect width. The strategy can reduce the wire resistance of Snaky Tango-Route March permutation to 8.99 ohm effectively, and control the standard deviation of wire resistance to 0.055 ohm in the physical layout implementation. Adjusting contact count of resistor node and make identical resistor node resistance in order to suppress Integral Nonlinearity error to 0.3215LSB.
