I have a theoretical understanding of the effect of noise from different transistor and variations in different transistor. I want to know how to simulate in cadence.
For for the differential amplifier -
1. Theoretically noise is done individually for each transistor and then added up. The final value will be in noise spectral density. The noise modelling of differential amplifier is shown in the Figure noise.
2. Threshold variations are considered as voltage difference in the inputs of gates and also shown in figure offset.
Now my question is how to realise this in cadence. I want to know how to get these parameters as from montecarlo analysis. Usually in data sheet, opamp variation and noise will be provided in terms of gaussian distribution. I want to get similar results through cadence simulation. Can anybody help me in this regard?
