Frequency Shift of a Relaxation Oscillator Due to an External Electrode
نویسنده
چکیده
The use of the properties of the plasma generated inside the glow lamps or gas filled electron tube as an unconventional detection method for various physical effects was reported in several papers. For example in [1], [2] the experimental setups containing discharge tubes used to detect the external microwave field are presented. In this paper the effect of an external electrode on the electrical characteristics of a gas filled voltage regulator tube is described. The change of the discharge properties is observed by measuring the oscillations frequency of a relaxation oscillator circuit. A similar method has been described in order to detect the optogalvanic effect [3–5].

The Transient Behavior of LC and Ring Oscillators under External Frequency Injection
In this work, time domain analysis is used to solve Adler’s equation in order to obtain the required time, for an oscillator under external injection, reaching the steady-state condition. Mathematical approach has been applied to fully describe the transient of frequency acquisition in injection-locked LC and Ring oscillators considering their time-varying nature. Then, the analysis is verifie...
متن کاملEffect of an external electrode on the characteristics of a low frequency discharge
The variation of the breakdown voltage of a low frequency electrical pulsed discharge due to an external electrode is reported. The discharge tube consists of a thin glass tube having two internal hollow electrodes. A thin copper foil wrapped around the glass tube forms the external electrode. The internal electrodes of the discharge tube are supplied by a flyback converter. Its operating point...

In this paper we investigate a biological framework to generate and adapt a motion pattern so that can be energy efficient. In fact, the motion pattern in legged animals and human emerges among interaction between a central pattern generator neural network called CPG and the musculoskeletal system. Here, we model this neuro - musculoskeletal system by means of a leg - like mechanical system cal...

This paper proposes a hybrid control scheme for the synchronization of two chaotic Duffing oscillator system, subject to uncertainties and external disturbances. The novelty of this scheme is that the Linear Quadratic Regulation (LQR) control, Sliding Mode (SM) control and Gaussian Radial basis Function Neural Network (GRBFNN) control are combined to chaos synchronization with respect to extern...
متن کاملA Sensitivity-Enhanced Film Bulk Acoustic Resonator Gas Sensor with an Oscillator Circuit and Its Detection Application
This paper presents a sensitivity-enhanced gas sensor based on a film bulk acoustic resonator (FBAR). It was designed and fabricated with micro through-holes in its top electrode for sensitivity enhancement. The sensor was driven by a Colpitts oscillator circuit, and the output signal had characteristics of a power of −2.6 dBm@3 V and a phase noise of −90 dBc/Hz@100 kHz. In order to test the pe...
