Flicker noise corner frequency calculation/simulation - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Hello,

I am trying to determine the flicker noise corner frequency for the BFR182 transistor.

Does anyone know the answer or perhaps can you direct me to literature that will teach me how to simulate it?

Thankyou,

Your help is very much appreciated.

Hi Darcy,

The flicker noise (also named 1/f noise or Pink Noise), is determined by internal characteristics of the transistor and is calculated by the simulator based on a SPICE model of the transistor.

Here is an application note which shows how to simulate this and other types of noise:

Good luck!
