TransistorAmp BJT Transistor Amplifier Circuits Designer Software 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.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 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. Select your desired transistor type there and click on OK. The selected transistor type will then be displayed in the dialog.
