Title:
CIRCUIT CONSTANT ANALYSIS METHOD AND CIRCUIT SIMULATION METHOD OF EQUIVALENT CIRCUIT MODEL OF MULTILAYER CHIP INDUCTOR
Document Type and Number:
WIPO Patent Application WO/2010/101197
Kind Code:
A1
Abstract:
The occurrence of errors between circuit design using a circuit simulator and the actual circuit performance is quite adequately suppressed. Mutual inductance (Lm) between inductance (L0) and inductance (L1) relative to DC is connected in parallel to a series circuit of the inductance (L1) and resistance (R1), the series circuit taking the skin effect of an inner conductor into consideration, and the inductance (L0), and DC resistance (Rdc1) of the inner conductor are connected in series to the series circuit to which the mutual inductance (Lm) is connected in parallel. Then, parasitic inductance (Ls) of an external electrode is connected in series to the equivalent inductance (L0), and DC resistance (Rdc2) of the external electrode is connected in series to the DC resistance (Rdc1) of the inner conductor. In addition, an equivalent circuit model which is configured by connecting a series circuit, in which parasitic capacitance (Cp), and resistance (Rp) indicating the loss of a dielectric body composing a chip are connected in series, to the inside of the equivalent elements (Ls, Rdc2) of the external electrode in parallel is used.
