Webelectronics). Then bipolar transistors have the ability to operate within three different regions: • 1. Active Region - the transistor operates as an amplifier and . Ic = β.Ib • • 2. Saturation -the transistor is "fully ON" operating as a switch and . Ic = I(saturation) • • 3. Cut-off -the transistor is "fullyOFF" operating as a ... WebThe BJT is a three terminal device and it comes in two different types. The npn BJT and the pnp BJT. The BJT symbols and their corresponding block diagrams are shown on Figure 1. The BJT is fabricated with three separately doped regions. The npn device has one p region between two n regions and the pnp device has one n region between two p …
