Operator-Splitting Methods for Neuromorphic Circuit Simulation

Amir Shahhosseini, Thomas Chaffey, Rodolphe Sepulchre

A novel splitting algorithm is proposed for the numerical simulation of neuromorphic circuits. The algorithm is grounded in the operator-theoretic concept of monotonicity, which be…

Graphical Dominance Analysis for Linear Systems: A Frequency-Domain Approach

Chao Chen, Thomas Chaffey, Rodolphe Sepulchre

We propose a frequency-domain approach to dominance analysis for multi-input multi-output (MIMO) linear time-invariant systems. The dominance of a MIMO system is defined to be the…

Amplitude response and square wave describing functions

Thomas Chaffey, Fulvio Forni

An analog of the describing function method is developed using square waves rather than sinusoids. Static nonlinearities map square waves to square waves, and their behavior is cha…

Analog cross coupled controller for oscillations: modeling and design via dominant system theory

Weiming Che, Thomas Chaffey, Fulvio Forni

We propose a new analog feedback controller based on the classical cross coupled electronic oscillator. The goal is to drive a linear passive plant into oscillations. We model the…

Oscillations in Mixed-Feedback Systems

Amritam Das, Thomas Chaffey, Rodolphe Sepulchre

A new method is presented for the analysis of limit cycle oscillations in mixed-feedback systems. The calculation of the limit cycle is reformulated as the zero finding of a mixed-…

Scaled relative graphs for system analysis

Thomas Chaffey, Fulvio Forni, Rodolphe Sepulchre

Scaled relative graphs were recently introduced to analyze the convergence of optimization algorithms using two dimensional Euclidean geometry. In this paper, we connect scaled rel…
