WebIn a BJT, only a tiny portion of current flows is due to majority carriers, while most are due to minority charge carriers. As a result, they are referred to as minority carrier devices. Equivalent Circuit Of BJT A diode is a symbol for a p-n junction. A transistor is equivalent to two diodes connected back to back since it has two p-n junctions. WebThe main function of a BJT is that a small voltage across (or current through) the base and emitter can control a relatively large current between the emitter and collector. This is … mapgrowth.comWebA BJT is a 3-terminal semiconductor device, as the name suggests, the term bipolar is taken from the truth that this kind of transistor includes two kinds of semiconductor materials like P-type (positive type) and n-type (negative type) where the current flows from these regions Usually, these transistors include Silicon. map growth login teacher

"WebBipolar Transistors. Michael Shur, in Encyclopedia of Physical Science and Technology (Third Edition), 2003. IV BJTs, FETs, and BiCMOS. Since BJT currents are exponential functions of the emitter–base voltage, a BJT transconductance (which is the derivative of the collector current with respect to the emitter–base voltage) is quite high compared to … " - In bjt current flows due to
