how to capture 1/f noise in spectre

pureck

Hello

 I am designing a down-converter and need to capture 1/f noise corner. I need to find a way to capture the corner automatically after simulation (PSS and Pnoise) instead of using rulers to find it.

Does anyone know how to grab it automatically?

 

Thanks much in advance.

    Hello Andrew,

     Thanks a lot. It works.

    One thing in flicker noise differs from PN is that it is 10dB/dec and we define 1/f noise corner at the point where a straight line (10dB/dec) of the flicker noise meets a horizonal line (0dB/dec) of the thermal noise as you may already know.

    Now it is a little difficult to decide the corner at what slope which can best interpret the real corner frequency. I guess it is up to designers' interpretation.

     Thanks a lot for your help.
