This work presents a 28nm deeply power-scalable reconfigurable series-resonance/Class-F VCO with mutual-inductance self-cancellation and hybrid 8-shaped coupling techniques, achieving power scalability from 5.7 to 93.1mW. By switching between parallel-resonance (Class-F) and series-resonance modes, the VCO achieves −149dBc/Hz PN and 192.8dBc/Hz FoM at a 10MHz offset. This design enables flexible PN–power scalability for Wi-Fi 7, IoT, and wearable devices.
