Amplifiers are crucial in every experiment carrying out a very sensitive measurement.
However, they always degrade the information by adding noise. Quantum mechanics puts a …

The design of analogue electronic experiments to investigate phenomena in nonlinear
dynamics, especially stochastic phenomena, is described in practical terms. The advantages …

We investigate the detectability of weak electric field in a noisy neural network based on
Izhikevich neuron model systematically. The neural network is composed of excitatory and …

Noise has already been shown to play a constructive role in neuronal processing and
reliability, according to stochastic resonance (SR). Here another issue is addressed …

We take a new look at an old problem; namely, the observed" noise rise" in superconducting
Josephson junction parametric amplifiers. By exploiting recent insights from dynamical …

We study the oscillator equations describing a particular class of nonlinear amplifier,
exemplified in this work by a two-junction superconducting quantum interference device …

We have investigated the performance of a resistive rf SQUID as a 9 GHz parametric
amplifier and oscillator. It was coupled to a low impedance microstrip transformer. Stable …

The noise-rise phenomenon is a long-standing problem that was first observed in
Josephson-junction-parametric amplifiers over ten years ago. We present here a case …

A systematic study of noise in a nondegenerate Josephson-parametric amplifier as it passes
through the threshold for oscillation was performed. Below the threshold all the noise is …

We study the general problem of small-signal amplification by globally coupled oscillator
arrays. The analysis is relevant, for example, to series-array Josephson-junction parametric …
