Abstract
This letter presents a switchable tri-core voltage-controlled oscillator (VCO) with 130% frequency tuning range (FTR). Utilizing the reconfigurable compensation stubs and reused varactors, three VCO cores are combined to achieve the switchable-free running frequency, while the FTR is greatly enlarged and the phase noise (PN) is almost unaffected.
