Analysis of Thermal and Shot Noise in Pumped Resistive Diodes

Abstract

This paper discusses certain important aspects of the noise behavior of a pumped resistive diode containing shot and thermal noise sources. The derivation of the following result has a central role in the discussion. It is shown that the noise behavior of a pumped diode which does not contain 1/f noise sources can be derived in a very simple way from Nyquist's theorem. This follows from the fact that the small‐signal terminal behavior of such a diode can always be represented, in the frequency range of practical interest, by means of a connection of two linear and time‐invariant networks of which one is noiseless and the other is dissipative, contains only thermal noise sources and is held at a uniform temperature.

Two-dimensional semiconductor device simulation of trap-assisted generation-recombination noise under periodic large-signal conditions and its use for developing cyclostationary circuit simulation models

“…We also simulate the cross-spectral densities (CSDs) between sidebands for both the case of diffusion noise and trap-assisted GR noise. Well-known results for the NCM for shot noise [3], [4] in junctions are verified using the simulator. In addition, we present simulation results which show good agreement between the modulated stationary noise model [15], [5], [6] for low-frequency noise in circuit simulation and microscopically cyclostationary GR noise sources in semiconductor device simulation.…”

“…This model has been used to describe the modulation of shot noise in diodes [3], [4] in circuit simulation and has been recently applied to the modulation of microscopic noise sources in device simulation [11]. This model applies when the correlation time of a noise process is much shorter than the period of an applied largesignal bias and is applicable to microscopic diffusion noise and GR noise phenomena.…”

“…While the conversion of shot and thermal noise is well understood and has successfully been modeled for circuit simulation using noise correlation matrices (NCMs) [3], [4], the modulation of -like low-frequency noise is still an open topic [5], [6]. This is, in part, due to the fact that such low-frequency noise can be attributed to a variety of sources [7].…”

Noise conversion of Schottky diodes in mm-wave detectors under different nonlinear regimes: modeling and simulation versus measurement

“…On the other hand, in general, apart from phase noise (PHN) in oscillators, simulation tool studies have paid limited attention to LF noise. Therefore, it is considered of great interest to have an accurate characterization of devices' LF noise together with reliable simulation tools for predicting its conversion to the system output, depending on the device operation regimes.The relevance of the device operation regime is shown in [3], which provides empirical evidence of the shot noise deviation with respect to the conventional model in a large-signal pumped Schottky diode, proposing an alternative model based, not on the mean current of the device, but on the smallsignal resistance, supported by a classic reference [4] and in agreement with the distinction between shot noise with constant and with time-varying rate presented in [5]. In [6], the simulation of cyclostationary noise is treated from a physically-based point of view.…”
