Is the quadrature oscillator a multivibrator? [PDF]

open access: yesIEEE Circuits and Devices Magazine, 2004
The aim of this article is to give insight into the mechanisms behind the behavior of oscillators from a new angle, introducing the idea of "frozen eigenvalues." This approach is based on piecewise-linear modelling and a study of the eigenvalues of the time varying linearized Jacobian of the nonlinear differential equations describing the oscillator. A

A Tunable Quadrature Oscillator with Only Transconductance Elements and Grounded Capacitors

open access: yesActive and Passive Electronic Components, 2002
A novel quadrature oscillator is realised with only transconductance elements (TEs) and grounded capacitors. The realised quadrature oscillator uses only two inverting and two non-inverting transconductance elements, along with two grounded capacitors ...

Simple quadrature oscillator for BIST [PDF]

open access: yesElectronics Letters, 2010
A simple quadrature oscillator for the built-in self-test (BIST) of integrated analogue filters is proposed. A new hardware-efficient approach for amplitude control is described, the main assets being: (i) the technique requires little hardware, which makes it very useful for BIST; (ii) the oscillation amplitude is well defined, and (iii) the ...
