Forum Post: Transient Current Noise vs AC current noise

$

Hello I am running noise analysis for a ramp generator. First I ran ac noise analysis (I set the operating points using actimes and ac names in tran options). Next I ran a transient noise simulation. I compared the current noise in both and they don't match (29uA in AC noise vs 60uA in transient noise). I did the same experiment for voltage noise, which seemed to match. I have attached a picture of my schematic. Regards Jatin
