—Computing the steady-state response of large non-linear circuits is becoming a key simulation requirement due to the rapid market growth of RF silicon integrated circuits. In this paper, we describe a nonlinear circuit reduction algorithm for finding the steady-state response. The proposed algorithm uses a congruent transformation-based technique to reduce(More)
With ever increasing clock frequencies, accurate 3-D interconnect analysis in chips and packages is becoming a necessity. The retarded partial element equivalent circuit (rPEEC) method has been successfully applied to 3-D analysis but for large problems at becomes expensive in CPU and memory usage, and in time domain it sometimes has numerical problems.(More)
—The increase of operating frequencies requires 3-D electromagnetic (EM) methods, such as the partial element equivalent circuit (PEEC) method, for the analysis and design of high-speed circuits. Very large systems of equations are often produced by 3-D EM methods and model order reduction (MOR) techniques are used to reduce such a high complexity. When(More)
An approach is introduced which improves published moment matching methods used in transient waveform estimation of large linear networks including lossy, coupled transmission lines. The method, which selects from a general set of moment-matching approm " mations, ensures stability while increasing the accuracy of the transient response, The developed(More)
