Describe the four biasing modes of operation
WebModes of biasing: Following are the different modes of transistor base biasing: 1. Current biasing: As shown in Fig.1, two resistors RC and RB … WebJan 24, 2024 · As the V CE passes the 0.7v, the base-collector PN junction becomes reverse bias. And the base-emitter is forward bias. 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.
