Parametric resonance based solutions for sub-gigahertz radio frequency transceiver with 0.3V supply voltage are proposed in this paper. As an implementation example, a 0.3V 720 μW variation-tolerant injection-locked frequency multiplier is developed in 90 nm CMOS. It features a parametric resonance based multi-phase synthesis scheme, thereby achieving the lowest supply voltage with -110 dBc@ 600 kHz phase noise and 873 MHz-1.008 GHz locking range in state-of-the-art frequency synthesizers.
