A 24GHz VCO with 20 tuning range in 130-nm CMOS using SOP Technology

摘要

A 24GHz System-on-Package (SOP) VCO is demonstrated. The core operates at 6GHz and employs a high-Q on-carrier inductor. Using two cascaded on-chip frequency doublers the centre frequency is 24.6GHz with a 20% tuning range. The phase noise is below -107dBc/Hz at 1MHz offset over the tuning range, with a FOM between 188 and 192dB at a power consumption of 6.9mW.
