Dynamic Behavior of FET Models

Joe Civello — Thu, 01 Mar 2012 17:34:16 +0000

One of the most common reasons for inaccurate large signal high frequency simulation results is the use of an inadequate non-linear device model. Consumers of such non-linear models should ideally know if a model they are using is suitable for the task before they commit a design simulated using that model to manufacture. However, given that models are most often generated by specialist modeling teams using dedicated hardware and software, the perceived hurdle both in expertise and time for qualifying a non-linear model is seen as very high and so few designers will even ask the question “Is my model good enough?” This application note describes a powerful simulation based device model qualification method that can allow a designer to test FET devices for critical large signal high frequency behavioral characteristics at the operating point required by his/her application. So, is your model good enough? Read on to find out. Dynamic-Behavior-of-FET-Models

New ADS Load Pull DesignGuide

Joe Civello — Fri, 24 Feb 2012 17:49:03 +0000

Andy Howard, ADS expert application engineer, has enhanced the ADS Load Pull DesignGuide. He has better organized the content, and added several load pull simulation setups, including one to enable designers to see how the optimal load impedance changes as the desired output power is stepped (using swept-power Maury data). He has also added some new and improved load mismatch simulations. These are useful when a power amplifier designer needs to see how much performance degradation occurs when the load is shifted away from its optimal value.

Supported ADS customers can download this updated Load Pull DesignGuide from the Agilent EEsof Knowledge Center: http://edocs.soco.agilent.com/display/eesofkcads/Load+Pull+DesignGuide+Enhancements+for+post+ADS+2011_10

The attached 10-page application note (ADS2011.10-Load-Pull-DG) shows updated DesignGuide in use including schematics and data display results.
