In LTspice, AC analysis involves computing the AC complex node voltages as a function of frequency using an independent voltage or current source as the driving signal. The small signal analysis results are plotted in the waveform viewer as magnitude and phase over frequency. AC analysis in LTsp...
Name the nodes asACSat the source side andACRat the response side. Enter the parameters for the ac sweep block. In the example, the perturbation source peak amplitude is 0.01V. Run LTspice simulation and view results in SIMVIEW.
The measured noise will actually be higher due to the band-pass filter cutoff frequencies. The LTspice simulation results assume a post processing brick wall filter to have a sharp roll-off at 20 Hz and 220 Hz. The command line in LTspice is then set to be .noise V(VOUT) V1 dec 100...
I recreated the schematic in LTspice and Qucs-S. I assume due to the extra voltage source V3 in 100W.sp is set up to use the Tian probe method. It is used to calculate Gain/Phase and the results are wrong. ivandi69 mentioned this issue Jan 20, 2024 Nutmeg script dialog improvements...
The problem is when i have to modify the Control Voltage in order to light my lamp in a fade-in effect. This is where i got stuck and i really don't know what to do. I'm simulating your circuit with LTSpice and Multisim and the results are different (especially when modifying the ...

A quick check of the AD8237 noise and ADA4505 noise determined that the AD8237 is the dominant noise source. Figure 3. An LTspice schematic. Figure 4. Transient simulation results. Figure 5. Transient simulation results zoomed in. Figure 6. AC simulation results. ...
