We propose a way to achieve quantum synchronization of two canonically conjugated variables. For this, we employ a superconducting device where the synchronization of Josephson and Bloch oscillations results in the quantization of transresistance similar to that in the (fractional) quantum Hall effect. An LC oscillator is a key component to achieve an exponentially small rate of synchronization...

Nowadays, the All-Digital Phase-Locked Loop (ADPLL) as a digital electronic circuit is applied in modern communication systems. The main components of ADPLL such as phase detector, loop filter and voltage controlled oscillator which are all digitally discussed in detail. On the other hand, sensitivity to parasitic mismatches in LC oscillators and the limitation of the robustness and the quantiz...

An apparent violation of the second law of thermodynamics occurs when an atom coupled to a zero-temperature bath, being necessarily in an excited state, is used to extract work from the bath. Here the fallacy is that it takes work to couple the atom to the bath and this work must exceed that obtained from the atom. For the example of an oscillator coupled to a bath described by the single relax...

In this paper, a dynamically coupled neural oscillator network is proposed for image segmentation. Instead of pair-wise coupling, an ensemble of oscillators coupled in a local region is used for grouping. We introduce a set of neighborhoods to generate dynamical coupling structures associated with a specific oscillator. Based on the proximity and similarity principles, two grouping rules are pr...

CMOS Scaling technologies are the main caused for great impact on Analog design. The most severe affect is the reduction in the voltage supply. A double balanced down conversion oscillator mixer using 90 nm CMOS technology is proposed in this work. This oscillator mixer consists of an individual mixer stacked on a voltage-controlled oscillator (VCO). The proposed stacked structure allows entire...

This paper discusses an analytical description of low frequency upconversion in LC oscillators. We show that upconversion into phase noise can be substantially reduced by modification of circuit topology. The theoretical discussion is supported by measurements of a 100 MHz BJT Colpitts model oscillator.

Based on a physical understanding of phase-noise mechanisms, a passive LC filter is found to lower the phase-noise factor in a differential oscillator to its fundamental minimum. Three fully integrated LC voltage-controlled oscillators (VCOs) serve as a proof of concept. Two 1.1-GHz VCOs achieve 153 dBc/Hz at 3 MHz offset, biased at 3.7 mA from 2.5 V. A 2.1-GHz VCO achieves 148 dBc/Hz at 15 MHz...

mission and sleep scheduling mechanisms for periodically gathering sensor data at a base station in wireless sensor networks. In our proposed mechanisms, we use a conventional self-organizing communication mechanism based on phase-locking in a pulse-coupled oscillator model to propagate sensor data from the edge of the network to the base station in order of hop counts from the base station. In...

Solar activity has an important impact not only on the intensity of cosmic rays but also on the environment of Earth. In the present paper, a coupled oscillator model is proposed in order to explain solar activity. Using this model the 89-year Gleissberg cycle can be naturally reduced. Furthermore, as an application of the coupled oscillator model, we attempt to apply the proposed model to the ...

This paper describes the optimization of phase noise performance in fully integrated SiGe HBT differential LC-tuned voltage-controlled oscillators (VCOs) for wireless applications. An accnrate expression for phase noise in SiGe HBT LC-tuned VCOs is presented which takes the nonlinear operation of the oscillator into account. Design methods are shown which minimize the different sources of phase...
