Circuit simulation is a fundamental enabler for the design of integrated circuits. As the design complexity increases, there has been a long lasting interest in speeding up transient circuit simulation using paralellization (Dong et al., 2008; Dong & Li, 2009b;c; Reichelt et al., 1993; Wever et al., 1996; Ye et al., 2008). On the other hand, Harmonic Balance (HB), as a general frequency-domain ...

In this paper, the Floquet theory is combined with harmonic balance for the in-depth analysis of a Chua’s family circuit, exhibiting intermittence. Floquet multipliers are calculated along the periodic solution paths obtained through harmonic balance by means of a continuation algorithm. The analysis of both the stable and unstable solution sections enhances the information about the system and...

In this paper we demonstrate the influence of models non-linearities to harmonic balance simulation software, such as Agilents’ ADS. Furthermore, we show how the large signal behavior in terms of convergence speed, time and region can be improved significantly. All methods proposed can be used for any kind of non-linear model, either analytical equations based or even table interpolated ones. I...

Period doubling bifurcation in buck converters is studied by using the harmonic balance method. A simple dynamic model of a buck converter in continuous conduction mode under voltage mode or current mode control is derived. This model consists of the feedback connection of a linear system and a nonlinear one. An exact harmonic balance analysis is used to obtain a necessary and sufficient condit...

The aim of this comment is to extend the study of the dynamics of a finite extensibility nonlinear oscillator conducted by Febbo [M. Febbo, A finite extensibility nonlinear oscillator, Applied Mathematics and Computation 217 (2011) 6464-6475]. We show that the linearized harmonic balance method is not sufficiently adequate for this oscillator and that the harmonic balance method without lineari...

A simple and efficient modified harmonic-balance technique is presented. This new algorithm is suitable for the large-signal time-dependent analysis of nonlinear millimeter wave circuits. The accurate design and successful implementation of very high frequency nonlinear circuits requires both a detailed understanding of the physical operation of the active devices and of how these nonlinear dev...

Dynamics and stability of average current-mode control of buck converters are analyzed by sampleddata and harmonic balance analyses. An exact sampled-data model is derived. A new continuoustime model “lifted” from the sampled-data model is also derived, and has frequency response matched with experimental data reported previously. Orbital stability is studied and it is found unrelated to the ri...
