Interplay between Excitability and Noise in Analog Spiking Neurons
Léopold Van Brandt, Alon Ascoli, Michele Bonnin +3
A spiking neuron is a dynamical system exhibiting a limit cycle (a spike) when subject to sufficiently excitatory input. Famous neuroscience experiments by Bryant and Segundo as we…
On the Excitability of Ultra-Low-Power CMOS Analog Spiking Neurons
Léopold Van Brandt, Grégoire Brandsteert, Denis Flandre
The excitability property of spiking neurons describes their capability to output an action potential as a real-time response to an input synaptic excitation current and is central…
Predicting State Transitions in Autonomous Nonlinear Bistable Systems with Hidden Stochasticity
Léopold Van Brandt, Jean-Charles Delvenne
Bistable autonomous systems can be found inmany areas of science. When the intrinsic noise intensity is large, these systems exhibits stochastic transitions from onemetastable stea…
Moments of Entropy Production in Dissipative Devices
Jean-Charles Delvenne, Léopold Van Brandt
We characterize the possible moments of entropy production for general overdamped Markovian systems. We find a general formulation of the problem, and derive a new necessary condit…
Stochastic Nonlinear Dynamical Modelling of SRAM Bitcells in Retention Mode
Léopold Van Brandt, Denis Flandre, Jean-Charles Delvenne
SRAM bitcells in retention mode behave as autonomous stochastic nonlinear dynamical systems. From observation of variability-aware transient noise simulations, we provide an unidim…
Variability-Aware Noise-Induced Dynamic Instability of Ultra-Low-Voltage SRAM Bitcells
Léopold Van Brandt, Jean-Charles Delvenne, Denis Flandre
Stability of ultra-low-voltage SRAM bitcells in retention mode is threatened by two types of uncertainty: process variability and intrinsic noise. While variability dominates the f…
The non-Landauer Bound for the Dissipation of Bit Writing Operation
Léopold Van Brandt, Jean-Charles Delvenne
We propose a novel bound on the mimimum dissipation required in any circumstances to transfer a certain amount of charge through any resistive device. We illustrate it on the task…
Noise-dissipation relation for nonlinear electronic circuits
Léopold Van Brandt, Jean-Charles Delvenne
An extension of fluctuation-dissipation theorem is used to derive a "speed limit" theorem for nonlinear electronic devices. This speed limit provides a lower bound on the dissipati…
Bounding Variance and Skewness of Fluctuations in Nonlinear Mesoscopic Systems with Stochastic Thermodynamics
Jean-Charles Delvenne, Léopold Van Brandt
Fluctuations arising in nonlinear dissipative systems (diode, transistors, chemical reaction, etc.) subject to an external drive (voltage, chemical potential, etc.) are well known…
