Bipolar Junction Transistor (BJT) – Formulas and Equations

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. In this circuit the base terminal of the transistor serves as the input, the emitter is the output, and the collector is common to both (for example, it may be tied to ground … Web• For a BJT to be biased in the active or linear operating region the following must be true: a. The base-emitter junction must be forward biased, with a resulting forward biased voltage of about 0.7v. b. The base-collector junction must be reverse-bias voltage being any value within the maximum limits of the device. http://www.learningaboutelectronics.com/Articles/Collector-region-of-a-bipolar-junction-transistor phosphate water testing kit

WebA Bipolar junction transistor, commonly known as BJT, is a Si or Ge semiconductor device that is structured like two p-n junction diodes connected back to back. It has two outer regions which are the emitter and collector and … WebSince the emitter is always roughly 700mV below the base, we also call this "emitter follower" because the emitter output follows the base input. Three terminals means three types: common emitter, common base, common collector/emitter follower.
