A low frequency oscillator structure

2009 European Conference on Circuit Theory and Design, 2009
We propose a novel RC sinusoidal oscillator architecture suitable for very low frequency generation. The oscillator is also attractive in the sense that the lower the oscillation frequency, the lower the necessary gain required to start oscillations. Further, the proposed architecture is active-circuit-independent and can be realized in any suitable ...

Observation of multi-scale oscillation of laminar lifted flames with low-frequency AC electric fields

Combustion and Flame, 2010
The oscillation behavior of laminar lifted flames under the influence of low-frequency AC has been investigated experimentally in coflow jets. Various oscillation modes were existed depending on jet velocity and the voltage and frequency of AC ...

Interaction of high-frequency and low-frequency oscillations in the synchronized oscillator

Radioelectronics and Communications Systems, 2015
Theoretical analysis of the oscillation synchronization under conditions of simultaneous low-frequency and high-frequency external impact on the oscillator has been conducted using an example of the generalized Van der Pol oscillator. It was shown that the interaction of high-frequency and low-frequency oscillations resulted in the appearance of ...
