In bjt current flows due to
Bipolar transistors have four distinct regions of operation, defined by BJT junction biases. Forward-active (or simply active) The base–emitter junction is forward biased and the base–collector junction is reverse biased. Most bipolar transistors are designed to afford the greatest common-emitter current gain, βF, in forward-ac… 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.

WebA 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. WebCharge flow in a BJT is due to bidirectional diffusion of charge carriers across a junction between two regions of different charge concentrations. By design, most of the BJT collector current is due to the flow of charges injected from a high-concentration emitter into the base where they are minority carriers that diffuse toward the collector ...
