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. WebDec 26, 2024 · Open-collector is a type of switched load driver circuit, along with open-emitter and push-pull. The terms 'open-collector' and 'open-emitter' are used when the switching component is a bipolar junction transistor (BJT), as collector and emitter are BJT terminals. If the switches are FETs, 'open-drain' and 'open-source' are used.

WebMay 22, 2024 · Figure 5.5.1: Collector feedback bias. To understand how feedback works, assume that a current is flowing from the supply, through RC, into the collector and finally, out of the emitter to ground. Via KVL, VCE = VC = VCC − IC ⋅ RC. Now suppose for some reason, a temperature change perhaps, β increases. This should cause an increase in IC.
