Fractional-Order Oscillator with Extended Control of Frequency of Oscillation
2020 43rd International Conference on Telecommunications and Signal Processing (TSP), 2020This paper presents a design of the fractional-order oscillator utilizing one Fractional-Order Capacitor (FOC) in its structure. The oscillator employs one FOC and two active elements referred to as Dual Controlled Transconductance Amplifiers (DCTAs) with electronically adjustable transconductance and also current gain.

Constant Frequency Oscillators*
Bell System Technical Journal, 1931The manner in which the frequency of vacuum tube oscillators depends upon the operating voltages is discussed. The theory of the dependence is derived and is shown to indicate methods of causing the frequency to be independent of the operating voltages. These methods are applied in detail to the more commonly used oscillator circuits. Experimental data

Pediatrics International, 1992
The current state of high frequency oscillation (HFO) in Japan is reviewed. The discussion is focused on the following: (i) the repeated application of short duration SI (sustained inflation) is effective in recruiting lung volume and increasing PaO2; (ii) HFO can prevent the formation of granulocytes related to lung injury; and (iii) HFO does not ...

Frequency Fluctuations in Noisy Oscillators
SIAM Journal on Applied Mathematics, 1985Summary: We study frequency and period fluctuations in a nonlinear oscillator driven by Gaussian white noise. We define the random period as the random time between two consecutive zero crossings by the random phase plane trajectory, and the random frequency as the number of such zero crossings per unit of time. These quantities are shown to be related

Parameter Finding Methods for Oscillators with a Specified Oscillation Frequency
2007 44th ACM/IEEE Design Automation Conference, 2007This paper presents a generalized formulation of the periodic steady-state analysis for oscillators. The new formulation finds the value of a circuit parameter that results in a desired oscillation frequency for the circuit. Numerical methods based on the time-domain finite difference and shooting methods, and the frequency-domain harmonic balance ...

2013 IEEE 56th International Midwest Symposium on Circuits and Systems (MWSCAS), 2013
In this paper, the oscillation frequency and waveform amplitude of a high frequency differential ring oscillator are analyzed and derived with a new platform. The obtained equations describe the nonlinear dependence of amplitude and frequency on the tail current, number of delay cell stages, and transistor sizes.

Vacuum Tubes as High Frequency Oscillators
Transactions of the American Institute of Electrical Engineers, 1934Vacuum tubes as oscillators and amplifiers at frequencies greater than 100 megacycles (3 m.) are considered in this paper. The type of construction used in a large number of different tubes, and the characteristics of the tubes, are presented. Circuits for operating the tubes also are considered and the theory of operation and the factors limiting ...

High-Frequency Oscillations in Schizophrenia
Clinical EEG and Neuroscience, 2011Neural oscillations and their synchronization may represent a versatile signal to realize flexible communication within and between cortical areas. There is extensive evidence that cognitive functions depending on coordination of distributed neural responses are associated with synchronized oscillatory activity, suggesting a functional mechanism of ...
