Publisher Summary This chapter discusses the modeling aspect of differential-algebraic
equations (DAEs). In computational engineering, the network modeling approach forms the …

Microwave modeling and simulation are essential to designing microwave circuits and
systems. Although fundamental concepts and approaches for modeling and simulation are …

Radio-frequency (RF) circuits exhibit several distinguishing characteristics that make them
difficult to simulate using traditional SPICE transient analysis. The various extensions to the …

We present a theory for reduced-order modelkg of finm time-varying systems, together with
efficientnumerid methods for application to large systems. me tecbrdque, died~ P (fime-V …

Widely separated time scales arise in many kinds of circuits, e, g., switched-capacitor filters,
mixers, switching power converters, etc. Numerical solution of such circuits is often difficult …

In electronic circuit and system design, the word noise is used to refer to any undesired
excitation on the system. In other contexts, noise is also used to refer to signals or excitations …

The history of RF and microwave computer-aided engineering is documented in the annals
of the IEEE Microwave Theory and Techniques Society. The era began with elaborate …

Issues related to substrate noise in system-on-chip design are described including the
physical phenomena responsible for its creation, coupling transmission mechanisms and …

This paper introduces a new, efficient technique for analyzing noise in large RF circuits
subjected to true multitone excitations. Noise statistics in such circuits are time-varying …

In this paper we present a preconditioned recycled Krylov-subspace method to accelerate a
recently developed approach for ac and noise analysis of linear periodically-varying …
