Circuit Analysis by a New Multirate Method

摘要

This paper proposes a new multirate analysis method which selects a proper numerical integration stepsize for each viriable in analyzing a circuit which has subcircuits with different rates. First a formulation technique of multirate circuit equations is derived. Then a rate classification technique is derived from the error estimation formula of the Backward Differentiation Formulas (BDF). Further a stepsize adjustment technique at a break point is explained.
