"Webtions are critical to the operation of the BJT. BJTs are also simply known as bipolar transistors. 8.1 INTRODUCTION TO THE BJT A BJT is made of a heavily doped emitter (see Fig. 8–1a), a P-type base, and an N-type collector. This device is an NPN BJT. (A PNP BJT would have a P+ emitter, N-type base, and P-type collector.) " - Bjt history

WebBJT Circuits • Most electronic devices take the signal between two input terminals and deliver from it an output signal between two output terminals. • The BJT has only three terminals so one of these is usually shared (i.e. made common) between input and output circuits. • We thus talk about common emitter (CE), WebIt is a switching device that can handle both electron and hole carriers. Since conductivity modulation is affected by minority carrier injection, BJT can handle larger current and current properties [1,2]. The circuit diagram uses the symbols E …
