How to evaluate the large-signal stability of power amplifiers?

iccb0309

Hi, everyone,

I am a student learning  to use Cadence' s suite of tools. I wonder how to evaluate the large-signal stability of power amplifier using Cadence' s design tools.

I know that Keysight's ADS software offers a method called WSprobe for assessing the large-signal stability of power amplifiers. But I am also interested in whether Cadence's suite of tools provides a similar functionality or if there are alternative, more effective methods for large-signal stability assessment. I have found that the Kf method is not suitable for our complex circuit, so I am seeking alternative solutions to ensure the stability of our circuits.

If such tools are available in Cadence, I also want to know the detailed information on how to use them, as well as their advantages and limitation. If there are no similar tools within Cadence's offerings, I would also like to know if there are any alternative suggestions or techniques that can help us effectively assess the large-signal stability of power amplifiers using Cadence tools.

Thanks a lot for help!

Regards,

Cai

  • Hi Cai,

    Microwave office offers a wide variety of stability methods for Power Amplifiers. Here you can find the simulation guide pdf: https://kb.awr.com/display/awrfaq/Documentation

    In the pdf, we have a section A.5. Stability Analysis Methods. Here you can find information regarding the different stability methods we offer.

    Also, if you click File -> Open Example and type stability, you will see some available built-in examples we have for different stability techniques and scenarios.

    Thanks,
