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.

A Quadrature RC Oscillator With Noise Reduction by Voltage Swing Control

, 2019
This 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

Mathematics
Hamiltonian 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.
