The low frequency 1/f noise in CMOS impacts the performance of analog and RF circuits such as high performance operational ampliers, low IF mixers and VCO phase noise. As the transistor area is scaled down, low frequency noise is Lorenztian-like and it exhibits more device-to-device variations. The variability in flicker noise is becoming increasingly important for circuits using very small transistors. It is thus necessary to develop a statistical compact model for flicker noise to enable a robust design of analog circuits. In this report, such a model is developed to describe statistical flicker noise behavior. The Statistical Flicker Noise Analytical Model is developed which includes analytical mean and standard deviation with a new model parameter. The model will predict noise magnitudes at given frequencies and yield percentiles.
