An 8-in. strip line trace is fabricated on an FR4 PCB with a width of 24 mils. It is separated from its ground plane by a spacing of 16 mils. Using the refined estimates of Figure 15.10 and Figure 15.16, calculate the strip line's parasitic capacitance per meter and inductance per meter. What is the strip line's characteristic impedance? If we want to lower the characteristic impedance, would we make the layer spacing from trace to ground larger or smaller? If we were constrained to a layer spacing of 16 mils, would we make the trace wider or smaller? If we increased the length of the trace to 16 in., what would happen to the characteristic impedance?
