I am working on noise reduction techniques. I need to know how cadence calculates noise parameters at back end. In my circuit I am doing PSS and PNOISE analysis and after that when I check noise summary it gives the over all noise with noise due to each transistor. But I need to check the proportion of different noises like thermal noise and flicker noise.
Apart from that I need to ask, does simulator assume that the noise due to different sources are non correlated and simply add the noise power from all transistors and calculates overall noise or the simulator checks whether noises are correlated or not ?
