Abstract
Various embodiments concern a method for forming a trace array by modeling a trace array having a plurality of traces, each trace having a plurality of trace segments corresponding to elements of a filter circuit having alternating high and low impedance elements. The alternating high and low impedance elements can correspond to inductors and capacitors. For each trace segment, a delay constant is measured between a plurality of nodes that are longitudinally arrayed along the trace segment. The delay constant can be a phase delay. The length of each trace segment is set based on the delay constant of the trace segment. The length of each trace segment can be set such that the trace has a linear group delay response across an operational frequency range of the flexure. A trace array is then formed based on the set lengths.
