WebThe BJT should be in the active region, to be operated as an amplifier. If appropriate DC voltages and currents are given through BJT by external sources, so that BJT operates in active region and superimpose the AC signals to be amplified, then this problem can be avoided. The given DC voltage and currents are so chosen that the transistor ...

WebJan 24, 2024 · This mode of operation is the active or linear region of operation in the BJT transistor characteristic curve. By increasing the V CE beyond 0.7v, the collector current remains constant for a given value of base current I B. Increasing the V CE can cause a very slight increase in I C because of the widening of the base-collector depletion region. WebJunction Breakdown - BJT has two diodes back-to-back. Each diode has a breakdown. The diode (BE) with higher doping concentrations has the lower breakdown voltage (5 to 10 V). In forward active region, BC junction is reverse biased. In cut-off region, BE and BC are both reverse biased. The transistor must withstand these reverse bias voltages.
