#207 Simulation of MOSFET noise with ngspice Issue created by 0y8w1x Environment • Klayout Version: not applicable • OS/Platform: Ubuntu 22.04 Actual Behavior I tried to do a noise simulation of a single common source transistor, but found the noise to be 0. In case the schematic is incorrect or I use the noise analysis wrong, please let me know. A simple DC analysis works just fine, so the general setup should be working. My circuit looks like this: Screenshot from 2024-09-22 20-55-08 And when I plot the onoise_spectrum/inoise_spectrum aswell as the total integrated noise I get the following: Screenshot from 2024-09-22 20-56-23 IHP-GmbH/IHP-Open-PDK
