    en.wikipedia.org/wiki/Common_collector

    Figure 1: Basic NPN common collector circuit (neglecting biasing details). In 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.

  6. BC548 - Wikipedia

    en.wikipedia.org/wiki/BC548

    The BC548 is a part of a family of NPN and PNP epitaxial silicon transistors that originated with the metal-cased BC108 family of transistors.The BC548 is the modern plastic-packaged BC108; [6] the BC548 article at the Radiomuseum website [7] describes the BC548 as a successor to the BC238 and differing from the BC108 in only the shape of the package.

    Energy band diagram of a simple NPN w:bipolar junction transistor under equilibrium showing electron energy versus position. The w:depletion regions of the emitter-base and base-collector junctions are marked.

  8. Sziklai pair - Wikipedia

    en.wikipedia.org/wiki/Sziklai_pair

    Alternately, if a germanium PNP device was used, it would have significantly different characteristics than the silicon NPN transistor. In the quasi-complementary topology, the performance of the lower pull pair, which uses a single NPN transistor, more closely matches the performance of the upper push pair, which consists of two NPN ...

  9. File:BJT PNP symbol (case).svg - Wikipedia

    en.wikipedia.org/wiki/File:BJT_PNP_symbol_(case).svg

    Description: PNP transistor symbol with case (IEEE 315). Note: A little confusing on the BJT page, because the NPN is drawn with Collector (C) on the top, while here it is drawn on the bottom.
