Abstract
In this work, a dual-mode oscillator built around a transformer-based resonator is proposed. By making use of this technique, a wideband VCO is designed that features a 69% tuning range spanning from 3.4 GHz to 7 GHz. An excellent 14.8 dB power-frequency-tuning-normalized figure of merit, accounting of -118.6 dBc/Hz phase noise at 1 MHz offset from the 4.6 GHz carrier at 1 mW power consumption, is reported
