BJT Voltage Amplifiers
The board allows a first approach to the theoretical practical study of the static and dynamic operation of the BJT (Base Âemitter Junction Transistor), used as a voltage amplifier. The board affords the problems associated to the use of the transistors in the three basic configurations: CE (Common Emitter), CC (Common Collector) and CB (Common Base). Firstly, the bias and the working point stabilization problems are considered. Then, the typical features of the three configurations are analyzed: input resistance, output resistance, voltage gain and current gain. In the second section of the board typical applications are studied, such as the bootstrap effect bias and the Darlington connection. The board is supplied complete with a set of stackable, plug in cables of suitable lengths and colours and with a training manual.
