On wafer de-embedding for SiGe/BiCMOS/RFCMOS transmission line interconnect characterization

Abstract

This paper compares different de-embedding techniques for on-wafer transmission line interconnect characterization. The main goal is to contrast and correlate de-embedded S-parameters and extracted electrical characteristics versus industry standard electromagnetic solver results. For the first time the simplified "thru" technique and new "short-open" method are employed for de-embedding on-chip coplanar waveguides over the 0.1-70 GHz frequency bandwidth.
