Thermodynamic Validity of Noise Models for Nonlinear Resistive Devices

چکیده

The rst result of this paper gives the shot-noise amplitude for a class of nonlinear resistances. The noise behavior for equilibrium and non-equilibrium bias conditions is uniquely speciied by the voltage-current relation and thermodynamic constraints. Secondly, we show that the Gaussian model cannot be applied to any nonlinear device. While the Gaussian model can be a useful approximation, it cannot be physically correct.

Nonlinear Device Noise Models: Satisfying the Thermodynamic Requirements - Electron Devices, IEEE Transactions on

This paper proposes three tests to determine whether a given nonlinear device noise model is in agreement with accepted thermodynamic principles. These tests are applied to several models. One conclusion is that the standard Gaussian noise models for nonlinear devices predict thermodynamically impossible circuit behavior: those models should be abandoned. But the nonlinear shot-noise model pred...

Thermodynamically valid noise models for nonlinear devices

Noise has been a concern from the very beginning of signal processing and electrical engineering in general, although it was perhaps of less interest until vacuum-tube amplifiers made it audible just after 1900. Rigorous noise models for linear resistors were developed in 1927 by Nyquist and Johnson [1, 2]. However, the intervening years have not brought similarly well-established models for no...

A Novel Resistive Capacitive Feedback Trans-impedance Amplifier Optimization Using IPSO Algorithm

A novel low noise trans-impedance amplifier is proposed using low cost 0.18 µm CMOS technology. A resistive-capacitive feedback is used to extend the bandwidth of the amplifier. As the structure is inductor less, it is suitable for low cost integrated optical interconnects. In this paper Improved Particle Swarm Optimization have applied to determine optimal trans-resistance and noise of propose...

Instabilities of the harmonic oscillator with fluctuating damping.

We investigate the instabilities of a linear damped oscillator due to fluctuations of the damping parameter. The fluctuations are driven either by Gaussian white noise or Poisson white noise (white shot noise). We consider three notions of stability. The first two are the well-known notions of stability in the mean and stability in the mean square. We introduce the concept of thermodynamic stab...
