Abstract--We compute power-voltage, power-current, and
causal definitions of the characteristic impedance of microstrip
and coplanar-waveguide transmission lines on insulating and
conducting silicon substrates, and compare to measurement.
Index Terms--Causal, characteristic impedance, circuit theory,
coplanar waveguide, microstrip.
I. INTRODUCTION
WE COMPUTE the traditional power-voltage and power-
current definitions of the characteristic impedance [1],
[2] of planar transmission lines on insulating and conductive
silicon substrates with the full-wave method of [3] and com-
pare them to the causal minimum-phase definition proposed in
[4]. Where possible we compare computed values of the causal
impedance to measurement. In all cases we find good agree-
ment. The microstrip simulations have been reported in confer-
