Phase noise in oscillators: a unifying theory and numerical methods for characterization

TL;DR: In this paper, the authors developed a solid foundation for phase noise that is valid for any oscillator, regardless of operating mechanism, and established novel results about the dynamics of stable nonlinear oscillators in the presence of perturbations, both deterministic and random.
Journal ArticleDOI

Hierarchical Modeling, Optimization, and Synthesis for System-Level Analog and RF Designs

TL;DR: The paper describes the recent state of the art in hierarchical analog synthesis, with a strong emphasis on associated techniques for computer-aided model generation and optimization, and surveys recent advances in analog design tools that specifically deal with the hierarchical nature of practical analog and RF systems.
Journal ArticleDOI

Analyzing circuits with widely separated time scales using numerical PDE methods

TL;DR: In this article, the authors present a mathematical formulation and numerical methods for analyzing a broad class of such circuits or systems, where the key idea is to use multiple time variables, which enable signals with widely separated rates of variation to be represented efficiently.

Hierarchical Modeling, Optimization, and Synthesis for System-Level Analog and RF Designs Small models, that represent the overall functioning of portions of large or complex circuits, can be generated by algorithms and used for system design and verification.

TL;DR: A detailed survey of algorithmic techniques for automatically extracting a suitable nonlinear macromodel from a device-level circuit can be found in this paper, with a focus on numerical techniques for handling the large number of degrees of freedom in these designs.
Journal ArticleDOI

Reduced-order modeling of time-varying systems

TL;DR: A key feature of this method is that it is capable of reducing time-varying linear systems, which enables it to capture frequency-translation and sampling behavior, important in communication subsystems such as mixers and switched-capacitor filters.
