"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. " - Bjt in active region
