You want to design a transistor amplifier and you search for a good method to do this. Perhaps you have already found some formulas in a book and you are confused and discouraged because of the complexity. Furthermore you need transistor parameters, e.g. from a data sheet and you are discouraged because of the effort, which is necessary for the calculation. The solution: Software TransistorAmp For the design of transistor amplifiers there is a new software available: TransistorAmp. With TransistorAmp you are able to create your individual transistor amplifier with a few mouse clicks. TransistorAmp is freeware. You can download the gratis-tool TransistorAmp here from our website: Download TransistorAmp Software. TransistorAmp is a program for Microsoft Windows and runs under Windows 2000, Windows XP, Windows Vista und Windows 7. How to use the software TransistorAmp The tool TransistorAmp has a very easy to use user interface. You start every design with the menu item "New Amplifier". In the pull-down-menu you choose your desired circuit. You can choose between common-base-circuit, common-emitter-circuit and common-collector-circuit. After that you get a dialog, where you have to put in all parameters of your amplifier. For the selection of the transistor type you can click on the button "Select transistor type from list", and you will see a list of all supported transistor types. TransistorAmp supports some thousand transistor types - even some Germanium transistors. Select your desired transistor type there and click on OK. The selected transistor type will then be displayed in the dialog. When you have completed your input in the dialog, you click on OK and see the result. You see a window with your input data, the circuit, the component values and the most important parameters of the operation point. If you want to change your design, you only need to click again on "New Amplifier" and the circuit in the pull-down-menu. The input data, which have given will be restored to the input dialog, and you can change one or more parameters. When you are satisfied with the result, you can click on "Result - Save". TransistorAmp saves all data which is displayed in the result window to a HTML-file. You can open this file with a browser (e.g. Firefox or Internet Explorer), inspect it and print it. I hope you will enjoy using TransistorAmp and wish you success with your projects.
