Research Interests and Projects

General Research Interests

Circuit design and analysis: analog, RF and microwave, ICs.
Circuit modelling and simulation: algorithms for steady-state, transient analysis and oscillator analysis, electrical-thermal simulation, transient analysis of frequency-defined components, nonlinear models, overall circuit simulator architecture.

fREEDA Simulator

A wave-based State-Variable Transient Analysis was implemented in 2009/10. A patch for fREEDA 1.4 to add the wave transient analysis (type: .wavetran) functionality, in addition to general bug fixes and convolution support for the Nport device can be downloaded below. The patched tree was succesfully compiled on Debian squeeze and Ubuntu (Lucid Lynx) and should compile with any new Linux distribution (gcc 4.4). The original fREEDA 1.4 source code is also provided below.

freeda-1.4w.patch.gz: Patch file
freeda-1.4.tar.gz: Full original source (patch not included).
MMIC-Soliton test netlist.

The patch can be applied as follows (assuming both files are downloaded in the current directory):

tar xvfz freeda-1.4.tar.gz
cd freeda-1.4
zcat ../freeda-1.4w.patch.gz | patch -p1
