Interactive Transistor Amplifier Applet
This applet is designed to show the DC "quiescent" behviour of a common emitter amplifier. Often the treatment of this system becomes a morass of mathematics for students, in which qualitative features become divorced from the detail of calculation. Thus this applet was created so that students (and teachers!) can gain an intuitive understanding for the behavior of such an amplifier. This page is not intended as a full treatment of transistor amplifiers or even an introduction; rather it is supplemental to other course materials.
