W. Heinrich et al., COPLANAR PASSIVE ELEMENTS ON SI SUBSTRATE FOR FREQUENCIES UP TO 110 GHZ, IEEE transactions on microwave theory and techniques, 46(5), 1998, pp. 709-712
This paper provides both modeling and design information on coplanar p
assive elements on silicon substrate, The influence of substrate resis
tivity on coplanar waveguide (CPW) loss is discussed, and elements of
a cell library for coplanar monolithic microwave integrated circuits (
MMIC's) on high-resistivity substrate are presented. The elements incl
ude discontinuities, junctions, and spiral inductors, The models are b
ased on field-theoretical simulations and verified by S-parameter meas
urements up to 110 GHz.
