Web26 apr. 2024 · What are the different modes of operation of BJT? The transistor can be operated in three modes: Cut-off mode. Saturation mode. Active mode. What is saturation mode electronics? When base-emitter junction is forward biased and base-collector junction is reverse biased we say the transistor is in operating in Active mode. WebThere are two most common transistor types today: the Metal -Oxide - Semiconductor or MOS and the Bipolar Junction Transistor or BJT. The MOS is also designated as MOSFET because it is a field effect transistor (FET). A great majority of both types are made from silicon (Si) and a small fraction (about 2%) from gallium arsenide (GaAs).

WebThe operating mode of a BJT is completely specified by these three variables. The three modes of operation are indicated in the figure. Cutoff and saturation modes occur when ic and vCE are very small, respectively.
