D1 + D2 / The «Study of the bipolar transistor box is a playful approach of this technology. The study deals with the characteristic values of the transistor and the design of an amplifier.
The practice is divided into two parts:
1. Study of the bipolar transistor in static mode and microwave small signal to determine the evolution of the currents, the gain and the cutt-off frequencies according to the polarization.
2. Design of an amplifier thanks to matching circuits to obtain a gain amplifier.
