What does Noise Analysis do?

When the noise analysis is run the simulator calculates the device noise and the total output equivalent input noise.

The device noise is the noise contribution propagated to a specified output node from every resistor and semiconductor device in the circuit. For semiconductor devices, the noise is broken down into the constituent noise contributions, where applicable. (Output as “shot” and “flicker” noise)

The Output Noise is the RMS sum of all of the device contributions propagated to a specified output node and the total output equivalent input noise is the equivalent noise that would be needed at the input to generate the calculated output noise assuming an ideal, noiseless, circuit.

The Noise Analysis needs to have the input source and output node set in the simulation profile.
