• Calibration of internal RC oscillator via UART • Synchronization/ calibration to within +/-2% of target frequency with a single synch-byte. • Alternate run-time synchronization/calibration to within +/-1% of target frequency with double synch-byte. • Support for all AVRs with tunable RC oscillator • 50% duty cycle required for correct synchronization/ calibration. • Enables robust UART commun...

Phase noise in mutually synchronized oscillator systems is analyzed for arbitrary coupling and injection-locking topologies, neglecting amplitude noise, and amplitude modulation (AM) to phase modulation (PM) conversion. When the coupling phase is chosen properly (depending on the oscillator model), the near-carrier phase noise is reduced to 1=N that of a single oscillator, provided the coupling...

Recent advances in understanding circadian (daily) rhythms in the genera Neurospora, Gonyaulax, and Synechococcus are reviewed and new complexities in their circadian systems are described. The previous model, consisting of a unidirectional flow of information from input to oscillator to output, has now expanded to include multiple input pathways, multiple oscillators, multiple outputs; and fee...

A single-crystal Nd:YAG fiber with polished and coated endfaces has been operated as a monolithic, guided-wave laser oscillator. The 47-microm-diameter, 7-mm-length fiber oscillator operated with a threshold of 3.7 mW and a slope efficiency of 10.5%. Seventy-five percent of the laser power was in the fundamental spatial mode.

We present results concerning aspects of quantum thermodynamics under the background non-Hermitian mechanics for dynamics a harmonic oscillator. Since better control over parameters in processes is desired, we use concepts from collisional model to introduce simple prototype thermal reservoir based on $\mathcal{PT}$-symmetric Hamiltonians and study its effects thermalization process single osci...

By using the generalized fractional analytical iteration method (GF-AEIM), single, double, and triple heavy baryons masses are calculated in hyper-central model two cases. In first case, potential is a combination of Coulombic potential, linear confining harmonic oscillator potential. second we add hyperfine interaction. The energy eigenvalues baryonic wave function obtained forms. present resu...

It is shown that the radiation field in a long-pulse, low-gain free-electron laser oscillator obeys the complex Ginzburg-Landau equation. The question of single-mode operation is investigated by analysis and simulation, and the results are compared with experiments at the University of California at Santa Barbara, as well as the Dutch fusion free-electron-maser experiment. It is shown that the ...

We present a model of the single-ganglion oscillator of the leech swim central pattern generator (CPG). The model is based on the known neuronal architecture of this circuit. Free parameters in the model were "tted to produce membrane potential oscillations matching those seen during swimming. However, the oscillations produced are not robust to small ($5%) changes in the parameters. We propose...

In its most basic form an oscillator consists of a resonator driven on resonance, through feedback, to create a periodic signal sustained by a static energy source. The generation of a stable frequency, the basic function of oscillators, is typically achieved by increasing the amplitude of motion of the resonator while remaining within its linear, harmonic regime. Contrary to this conventional ...
