Bjt is a controlled device

WebMar 6, 2015 · Hence, the BJT cannot be used as avoltage-controlled resistor. However the situation is completely different for FET´s in particular for JFET´s. These devices have another working principle than BJT`s - they can be seen as voltage controlled resistors within the so-called "linear" region (ohmic region) for rather small VDC values (up to 1V). WebBJT stands for Bipolar junction transistor. B = Bipolar (because conduction is due to two opposite type of carriers Holes and electrons); J = Junction refers to the two PN junctions …
