Nonlinear Analysis of a Cross-Coupled Quadrature Harmonic Oscillator [PDF]
, 2004 We derive the dynamic equations governing the cross-coupled quadrature oscillator leading to an expression for the trade-off between signal quadrature and close-in phase noise.

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 Based Neural Network Learning of Stochastic Hamiltonian Systems
MathematicsHamiltonian Neural Networks (HNNs) provide structure-preserving learning of Hamiltonian systems. In this paper, we extend HNNs to structure-preserving inversion of stochastic Hamiltonian systems (SHSs) from observational data.

Two integrator loop quadrature oscillators: A review
Journal of Advanced Research, 2013 A review of the two integrator loop oscillator circuits providing two quadrature sinusoidal output voltages is given. All the circuits considered employ the minimum number of capacitors namely two except one circuit which uses three capacitors. The circuits considered are classified to four different classes.
