WebJan 13, 2024 · A Bipolar Junction Transistor (BJT) is a current-controlled semiconductor device which has three-terminals. The current in BJT is carried by both majority and minority carriers so it is known as bipolar device. The input resistance of BJT is low so it is used as an amplifier, oscillator circuits and digital circuits. Contents show WebIt is called the operating point because the variations of Ic and Vce take place at this point when an input signal is applied. This point is also called as Q point or quiescent (Silent) point because it is a point of output characteristics when a transistor is silent i.e. in absence of the signal. For operating point, we have to find load line. cste congenital syphilis case definitionWeb1.Fixed bias (base bias): The single power source (for example, a battery) is used for both collector and base of a transistor, although separate batteries can also be used.
