mos noise
We know the channel noise of MOSFET can be expressed as 4kTγgd0(γ=2/3 for long channel). When it comes to deep sub-micro technology,its value is much higher than 2/3.
The question is when I simulate the LNA noise figure in spectre RF, according to the simulated results, I found γ is much closer with 2/3. I wonder how the simulator calculates this parameter. and whether we could trust this result.
Thanks
