A Low Phase-Noise Wide Tuning-Range Quadrature Oscillator Using a Transformer-Based Dual-Resonance Ring

This paper presents a dual-band quadrature voltage-controlled oscillator (QVCO) using a transformer-based high-order LC-ring resonator, which inherently provides quadrature signals without requiring noisy coupling transistors as in traditional approaches, thereby achieving low phase-noise performanc...
