noise analysis for RF IC

what are u working on ? trying to find nf ?

it is frequency sysnthesiser based on PLL integer N

You can simulate the noise performance of each PLL block and calculate the contribution to the PLL output then add them up.

the noise analysis will depend on ur cicuit , is it a mixer , LNA , VCO and so on

khouly

sorry! i coludn't help you!

can you specify functions for calculating individual block noise contribution.

the full PLL noise analysis? can it be done using dft function.
