WebThe term bipolar refers to the use of both holes and electrons as current carriers in the transistor structure. Figure 1: Basic BJT structure. The pn junction joining the base region and the emitter region is called the base-emitter junction. The pn junction joining the base region and the collector region is called the base-collector junction.

WebFeb 10, 2024 · To work as an open switch, a BJT operates in cut-off mode, here there is zero collector current, meaning ideally zero power is consumed by the BJT. On the other hand, to work as a closed switch, a BJT works in saturation mode, there are a high collector current and zero collector voltage, meaning ideally there is zero power consumed by the BJT.

WebMay 22, 2024 · When acting as an open (non-conducting) switch it is acting as an amplifier amplifying a signal of zero. When acting as a closed switch (conducting) it is acting as an amplifier trying to amplify the largest signal it can.
