A study on design of differential-paired lines with meander delay line by preference set-based design method

In the design of electric and electronic devices, it is required to pursue a solution which satisfies simultaneously multi-objective performances sometimes including conflicting requirements. This paper newly attempts to propose a concurrent design method in electrical and electronic engineering by applying a multi-objective satisfactory design method, Preference Set-Based Design (PSD), to differential-paired lines with meander delay line. The meander delay line for the equi-length routing are designed using PSD. The design parameters satisfying required performances are obtained in ranges successfully. The validity of the design parameters is demonstrated by numerical modeling. It was demonstrated that PSD is applicable for multi-objective design under the uncertainty problems.
