✦ Synopsis

Abstract

Design methodologies of CMOS transmission lines (T‐lines) and resonators at millimeter‐wave frequencies are presented. Three different T‐lines including thin film microstrip line, coplanar waveguide, coplanar waveguide with ground, are designed and fabricated in standard 0.18‐μm CMOS technology. After on‐wafer testing to 40 GHz and SLOT de‐embedding calibration, their S‐parameters are extracted and analyzed. To achieve a small size, meandering quarter‐wavelength line resonator and stepped impedance resonator resonating near 30 GHz are designed, with their Q‐factor of 12 and 10.5, respectively. A good agreement between the predicted and measured results has been observed up to 40 GHz. © 2008 Wiley Periodicals, Inc.
