Concept explainers

BJT (Bipolar Junction Transistor)

A BJT is a semiconductor device with 3 terminals that consist of a p-n junction diode that can amplify the signal or current. It is a current-controlled device. The three BJT terminals are base, collector, and emitter. The BJT works with the charge carrier, the two type of carriers in the BJT are holes and electrons, the charge carriers flow by the process of recombination. The signal to be amplifier is generally given as the input at the base terminal and an amplified form of it is available at the collector terminal.

A transistor amplifier circuit is biased so that the quiescent point is to the far left of the load line midpoint. What do you expect to occur when the input voltage begins to vary? O The output voltage will be distorted on the bottom because it will hit the lower limit for VCE before the input voltage arrives at its peak. The output voltage will be distorted on the top because it will hit the upper limit for VCE before the input voltage arrives at its peak. O The output voTransistor's output voltage will look like the input voltage amplified and inverted. The output voltage will be zero (flat).
