A Digitally-Calibrated Phase-Locked Loop With Supply Sensitivity Suppression
—A digitally-calibrated technique to suppress the supply voltage sensitivity of a phase-locked loop (PLL) is presented. The voltage-controlled ring oscillator with an additional ...

Macromodelling oscillators using Krylov-subspace methods
— We present an efficient method for automatically extracting unified amplitude/phase macromodels of arbitrary oscillators from their SPICE-level circuit descriptions. Such com...

Moment-based analysis of synchronization in small-world networks of oscillators
— In this paper, we investigate synchronization in a small-world network of coupled nonlinear oscillators. This network is constructed by introducing random shortcuts in a neares...

Neuronal Multistability Induced by Delay
Abstract. Feedback circuits are important for understanding the emergence of patterns of neural activity. In this contribution we study how a delayed circuit representing a recurre...

PV-PPV: Parameter Variability Aware, Automatically Extracted, Nonlinear Time-Shifted Oscillator Macromodels
Abstract-- The PPV is a robust phase domain macromodel for oscillators. It has been proven to predict oscillators' responses correctly under small signal perturbations, and ca...
