A Low-power Low-noise Quadrature Relaxation Oscillator
, 2021 DoctorThis paper presents a low power and low noise quadrature RC oscillator based on a frequency locked loop. Voltage swing control of each of the two sub-oscillators reduces the effect of 1/f noise on the accumulated jitter.

Quadrature Mixer LO Leakage Suppression Through Quadrature DC Bias [PDF]
, 2002 A new concept has been developed which allows direct-to-RF conversion of digitally synthesized waveforms. The concept named Quadrature Error Corrected Digital Waveform Synthesis (QECDWS) employs quadrature amplitude and phase predistortion to the complex

A high-frequency electronically tunable quadrature oscillator
IEEE Journal of Solid-State Circuits, 1992 An architecture composed of mutually regenerative oscillators is introduced. It has been used to design a low-noise high-frequency voltage-controlled oscillator (VCO) capable of producing two output signals in quadrature with essentially identical properties. The phase relation between the quadrature outputs is frequency dependent and extremely stable.
