    How to measure additional noise contribution from the frequency multiplier and/or divider circuits? Reply
    I know that the frequency multiplier and/or divider degrades/improves the phase noise of the input sinusoidal source by 20*logN. But is there a way to measure the additional noise contribution from the multiplier/divider circuits themselves in the overall frequency translation?

    Hi Howhowhow,
     
    Have you looked at the Pnoise summary?

    Thank you, Tawna,

     

    I did look at the PNoise summary and see the contribution but my question is more geared towards the residual phase noise of the frequency multiplier and divider?

    Regards,
