Design, modelling and characterization of transmission lines for mm-wave silicon ICs

Abstract

This paper describes the design, modelling and characterization of transmission lines for millimetre wave silicon integrated circuits up to 65 GHz. The simulation results of three different EM simulators for a selected hybrid coplanar layout structure are presented. Two different deembedding methods are investigated and compared with respect to sensitivity to typical measurement errors. Finally both methods are applied to the measurement results of the fabricated test structures in a 250 nm BiCMOS technology showing good agreement to EM simulations and predicted sensitivity to measurement errors.
