Hi,

I wonder, In the data sheet, how the last term in Eq. 108 is derived. According to the model from Ray Ridley, the high frequency term is

And in the Eq. 108, the high frequency term is

Compare the two above, it seems the Q in the example is chosen to be 1, right? Can someone prove it in some math equations?

    Hello Diverger

    Unfortunately the equations did not appear in the post - can you re-post.

    You will need to create an image of the equations and thenuse the paperclip icon to insert it into the post - I'm sorry - you are not the first person to be caught by this.

    Regards
