Peek Inductor

Description: Spiral Inductor PEEC Model

Figure 1: Spiral inductor with part of overhanging copper plane

The description of the PEEC model of a spiral inductor can be found in PeekInductor.pdf.

The complex impedance is:

$Z(w)=Resis(w)+i*w*Induc(w)=G(i*w{)}^{-1}=(B^{⊺}(-A+i*w*E{)}^{-1}B{)}^{-1}$

A plots of $Resis(w)$ can be found in PeekInductor-Rspiral_skin.pdf and a plot of $Induc(w)$ in PeekInductor-Lspiral_skin.pdf.

Origin

This benchmark is part of the Oberwolfach Benchmark Collection; No. 38891, see .

Data

The model is of order $N=1434$ and of the form:

$\begin{array}{rcl}E\dot{x}(t)& =& Ax(t)+Bu(t)\\ y(t)& =& B^{⊺}x(t)\end{array}$

and can be downloaded as PeekInductor-dim1e3-spiral_inductor_peec.tar.gz (10.5 MB).

Short Matlab files to:

• plot $Resis(w)$ and $Induc(w)$,
• perform a PRIMA reduction of order 50,
• produce symmetrized standard state-space system: $\dot{x}(t)=A_{symm}x(t)+B_{symm}u(t)$, $y(t)=B_{symm}^{⊺}x(t)$, where $A_{symm}$ is symmetric.

Dimensions

System structure:

$\begin{array}{rl}E\dot{x}(t)& =Ax(t)+Bu(t)\\ y(t)& =B^{⊺}x(t)\end{array}$

System dimensions:

$E\in {\mathbb{ℝ}}^{1434\times 1434}$, $A\in {\mathbb{ℝ}}^{1434\times 1434}$, $B\in {\mathbb{ℝ}}^{1434\times 1}$.
