A Novel Phase-Noise Module for the QUCS Circuit Simulator. Part II : Noise Analysis
Torsten Djurhuus, Viktor Krozer
The paper documents the implementation of a novel phase-noise analysis module within the open-source QUCS circuit simulator environment. The underlying algorithm is based on a rigo…
A Novel Phase-Noise Module for the QUCS Circuit Simulator. Part I : the Periodic Steady-State
Torsten Djurhuus, Viktor Krozer
The paper discusses work done to expand and extend the capabilities of the open-source QUCS circuit simulator through the implementation of a computationally efficient time-domain…
A Novel First-Principles Model of Injection-Locked Oscillator Phase Noise
Torsten Djurhuus, Viktor Krozer
The paper documents the development of a novel time-domain model of injection-locked oscillator phase-noise response. The methodology follows a first-principle approach and applies…
Conditions for Oscillator Small-Signal Amplitude-Phase Orthogonality
Torsten Djurhuus, Viktor Krozer
The paper explores a previously unknown connection relating the symmetry properties of an oscillator steady-state to the orthogonal representation of amplitude and phase variables…
