WebThus, the BJT transistor consists of two pn junctions, connected back-to-back. These are called the emitter-base junction (EBJ) and the collector-base junction (CBJ). The circuit symbols for both kinds of BITs are shown in Figure 1. BJTs are asymmetrical devices, i.e. the collector and emitter regions are dissimilar.

WebMay 22, 2024 · One of the more useful BJT device plots is the family of collector curves. This is a series of plots of collector current, IC, versus collector-emitter voltage, VCE, at varying levels of base current, IB. To generate these curves we drive the base terminal with a fixed current source establishing IB. WebIn electronics, a common collector amplifier (also known as an emitter follower) is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a voltage buffer .
