017_dot_noise : dot Noise analysis

Requires: SmartSpice & Smartview

Minimum Versions: SMARTSPICE 3.16.12.R

First we can look at the simple .noise analysis of a resistor to see the characteristic over frequency. Take input deck and run in SmartSpice saying YES to run all alter cases. Two simulations are run and then you can select the noise vectoor to plot as shown in this view of the vector wuindow. You will then get a plot of waveforms that show the low frequency 1/f increasing noise level with lower frequency and the other flat line showing just the thermal noise contribution.
