Design and modeling of on-chip planar capacitor for RF application

On-chip radio frequency (RF) capacitor is one of the key components for RF integrated circuit (RFIC) designs such as filters and oscillators. Several researches on the design of on-chip planar capacitor have been reported. However there is a need to modify the existing synthesizing procedure; model...
