1. Selecting a transistor model from the database
Select a transistor model (see Figure 2).Figure 2 – Searching for and selecting a transistor model
Select a transistor model (see Figure 2).Figure 2 – Searching for and selecting a transistor model
Under the label "Input transistor model" type the transistor model name in the input field using Latin characters (case-insensitive), as indicated by the arrow in Figure 2 above. If the model is found in the database, it will be displayed in the list on the left under the label "Model Search" Once the model is found, you can proceed with the preliminary amplifier calculation. Click the "Calculate" button located to the left of the input field, and the program will perform the preliminary calculation of the amplifier stage.
Note to Step 1:
If the model is not found, you can search for transistor equivalents; it is quite possible that they will be available in the software database.
