WebTransistors, used to amplify and switch signals, heralded the modern electronics era. Two predominate transistors today include Bipolar Junction Transistors (BJT) and Metal-Oxide-Semiconductor Field Effect Transistors (MOSFET). MOSFET offers advantages over BJT in modern electronics and computers. 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).
