In the Model box, put the filename that contains the circuit; in this case MIC4422.SUB Once you put this value in Model, you no longer have to use .INC modelname in I dont seem to be able to attach an asc file like you have to your replyClick to expand... I go into where it is in the LTspice folder and i dont see any asc files Click to expand... I'll certainly be checking that out. http://www.electro-tech-online.com/threads/ltspice-problem.94245/

Vielen Dank schonmal.
I used a .lib statement to include the transistor, with the model name mmbt3904lt1g instead of qmmbt3904lt1g. :\ –Seth Shill Aug 8 at 17:20 add a comment| active oldest votes Know The two .inc files need to be in the same folder as the schematic (.asc) file. But when I try to run it, there is an error: Could not open library file "C:\Users\carmelovicari\Documents\DATI..." To be clear I am not this Carmelo Vicari (must be someone from ST), that brought you and continues to bring you LTSpice.
There are 2 types of model that can be imported into LTspice: .MODEL parts - these are simple components such as transistors and diodes .SUBCKT parts - these are more Ltspice Add Model FIG 2 The final circuit should look like FIG 3 FIG 3 Run the simulation.

Running the simulation shows the output falls to 0.707V at about 10kHz, showing the inferior frequency response of the LM324 over the LT6231.
