implement noise behavior of transistor in spice code in spectre

Hi,

It's very nice to be here. I got several problems solved by reading the threads here.

But there are some more as is always the case when I try to learn something new.

So I did dc and ac simulation with a very simple common source amplifier (See attached picture.). I used the generic nmos transistor in analoglib and used a model card (level=1, thus mos1 model) for the nmos model. 

Those simulations were successful. 

Further, I want to study the output noise of the circuit. And I would also like to replace the nmos model with RPI polysilicon TFT models.

In the mos1 model, there are no parameters available for noise. The same case goes for poly-Si TFT models. How can I implement the noise model? I want to include flicker noise and channel noise. Some literature suggested writing a spice code to do this. I just don't know how it's worked out in cadence.

Thank you for your time.

Bo
