Hi, I am a girl who has 2 questions for you. What is harmonic balance? And is it possible to make ADS to work with Matlab?

Hello,

Harmonic Balance is a method to solve non-linear circuits. The circuit is being analyzed according to Kirchoff's law by injecting N tones to it. The currents and voltages are then being calculated for each tone. This method can be implemented for active devices only if they are provided with their Spice model, since this model allows non-linear analysis.

Harmonic Balance lets you find out various parameters as: IP3, P1dB etc.

Regarding ADS and Matlab, as far as I know they can't be working together.

ADS works with Matlab well in ptolemy simulation environment.

Ptolemy can be a top-level simulation co-simulating with circuit envelope and matlab. Do you want both HB and matlab in the same simulation ?
There are different ways of doing things in ADS. Sometimes, it may also be possible to save the results of one simulation in a file(sink type=file) and then use that file as a source in 2nd simulation.


Good luck,

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
