WebMar 11, 2024 · For an NPN transistor, it consists of a layer of P-doped semiconductor between two layers of N-doped material, where electrons are passed from the emitter to the collector instead. The emitter then “emits” electrons into the base, with the base controlling the no. of electrons the emitter emits. The emitted electrons are finally collected ... Webtransistors. 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 …
