z = \frac{{87}}{{\sqrt{{e + 1.41}}}} \cdot \ln\left(\frac{{5.98h}}{{0.8w + t}}\right)
c = \frac{{2.64 \times 10^{-11} \cdot (e + 1.41)}}{{\ln\left(\frac{{5.98h}}{{0.8w + t}}\right)}}
p = 3.34 \times 10^{-9} \cdot \sqrt{{0.475e + 0.67}}
l = c \cdot z^{2}
where,
- z = Characteristic Impedance
- e = Relative Permittivity
- h = Height of Dielectric
- w = Width of Trace
- t = Trace Thickness
- c = Capacitance per unit length
- p = Effective propagation delay
- l = Inductance per unit length
