Abstract

High quality factor configurable inductors are critical components for robust multiband wireless applications. Configurable Multilayer Coplanar Wave Guide (MCPW) based inductors in nano-scale CMOS technologies are proposed in this paper for millimeter wave frequency applications. Inductors are tweaked by adjusting the transmission line length to compensate for process variations of the mm-wave circuits and cover multiple bands. For demonstration, a mm-wave Voltage Controlled Oscillator (VCO) using the configurable inductor was designed and fabricated. Measurement reveals that the VCO covers frequency ranging from 72.8 to 77.6 GHz with phase noise of -109 dBc/Hz at 10 MHz offset, which is in good agreement with the MCPW-based inductor model prediction.
