WebLTspice can perform .noise analysis of a circuit, where the noise voltage density (V/√ Hz) for 1Hz bandwidth) can easily be plotted for the output noise, input noise or for any noisy component like a resistor, diode or transistor. However, you can also easily integrate noise over a selected bandwidth in a .noise analysis. Figure 1.
WebMay 22, 2024 · Note that LTspice changes the name of the output plot to “V(onoise)”. The plot shows a flat line at 9.1 nV/Hz 1/2. This is the total of all the individual noise sources added together in an RMS fashion to produce the noise at the output. The vertical axis has units of nV/Hz 1/2.
