description An apparatus for radio-frequency (RF) oscillation signal production is disclosed. In example implementations, an apparatus includes an oscillator. The oscillator includes multiple oscillation stages that are coupled together in series into a ring. A respective oscillation stage of the multiple oscillation stages includes a transconductance amplifier and a core oscillator. The transconductance amplifier is coupled to a preceding oscillation stage. The core oscillator is coupled to the transconductance amplifier and to a succeeding oscillation stage, with the core oscillator including at least one output node configured to provide a respective output signal. In some implementations, at least one capacitor is coupled across at least the transconductance amplifier. In some aspects, at least one transistor of the transconductance amplifier is implemented with a silicon-on-insulator metal-oxide-semiconductor (SOI MOS) device that includes at least one back-gate terminal.
