Dear Analog Insydes User,

welcome to the first issue of the Analog Insydes Newsletter. This
service is provided to you by ITWM to keep you informed about the
latest news and developments concerning our circuit analysis and design
toolbox Analog Insydes(tm) for Mathematica(r).


1. Program patches now available on the web
===========================================

On the Analog Insydes web site you will now find a page with bugfixes
for Analog Insydes Release 1.0 program modules:

www.itwm.uni-kl.de/as/products/ai/patches.html

To install a patch, download the .m file (Internet Explorer:
right-click on the link and select "Save link as...") and replace the
corresponding Analog Insydes program module on your disk by the new
file. See Section 2 for a description of available patches.


2. New patches
==============

- Approximation.m (Revision 1.13.2.3)

This patch fixes some problems with numerical instability of the
symbolic matrix approximation algorithm. Numerical errors sometimes
caused ApproximateMatrixEquation to become trapped in infinite loops or
let matrix singularity remain undetected. The patch contains an
improved algorithm for computing the influences of matrix entries which
is numerically more reliable.
IMPORTANT NOTE: Revision 1.13.2.3 replaces Revision 1.13.2.2, which
was available on the patch page until Nov. 9, 1998. If you already
downloaded Revision 1.13.2.2 please make sure that you install the
newer version.


- ModelLibrary.m (Revision 1.8.2.1)

This patch fixes a minor bug in the device model library. In the MOSFET
model VoigtLevel1 the variable B1Null was incorrectly expressed in
terms of the parameter GAMMA instead of LAMBDA.


3. New demo notebooks
=====================

Did you ever wish you could actually *listen* to circuit simulation
results? If so, take a look at the notebook Distortion.nb, now
available on the "Demos" page:

www.itwm.uni-kl.de/as/products/ai/demos.html

Have fun!
