Abstract :
An area-efficient U-shaped slow-wave coplanar waveguide (U-SCPW) in a standard 0.18 μm CMOS process is presented. Compared to a conventional straight line CPW (S-CPW), it provides a more compact layout because of its approximate 1:1 aspect ratio. Measured results show that it has a quality factor and phase velocity comparable to its straight-line counterpart with measured Q ~ 30 at 23 GHz.
