Broadband Measurement of Asymmetric Coupled Lines Built in a 0.25 µm CMOS Process

Abstract
This paper examines the properties of asymmetric coupled lines built in a 0.25 um CMOS technology over the frequency range of 50 MHz to 26.5 GHz. We show that the frequency-dependent line parameters extracted from calibrated four-port scattering-parameter measurements agree well with numerical predictions.
