I am trying to design an amplifier by using CA3086 npn transistor and simulate it in proteus, but this transistor model does not exist in its library. Do you know where I can find it and add to library , because only related other models are the ones with MOSFETs.
CA3086 has three transistors with individual BCE pins and one couple that has the emitters connected together.
The model you have is for a single transistor, you can either make the transistor and place it in the schematic as many times as you want or you can make the original case, the result will be the same for simulation.
