Hello,

Can someone explain to me what large signal noise is? How does that translate into bias noise? I haven't been able to find any useful information on the topic from googling it.

Thanks
 

not sure what you mean. In a FET, when you hit the gate with a large signal, you can excite "Traps" at the edges of the depletion layer that temorarily store electrons, and later randomly release those electrons...adding to the phase noise. I remember a grad student thesis from UMASS Amherst in the USA on this effect from the '80s--the amount of noise added was gate bias dependent.

you can google traps, but here is one paper
