Difference between AntennaAreaRatio and AntennaDiffAreaRatio

archive

 Hi All ,

 

What is the difference between  AntennaAreaRatio and AntennaDiffAreaRatio ? 

 

Thanks in advance.

  • If there is a connection between the input pin and diffusion through the current layer being evaluated or below, then AntennaDiffAreaRatio is used. Otherwise, AntennaAreaRatio is used. AntennaDiffAreaRatio is always larger because the diffusion provides a discharge path.

    A good chapter on antenna calculations can be found here:
