WebSep 7, 2024 · Reverse-active: The Reverse-active region occurs when the transistor is in its active state but the maximum current gain in the reverse active mode is much smaller than the forward active mode. The biasing conditions are reversed so that the base collector junction is forward biased and the base emitter junctions is reverse biased, which ... WebFor a proper functioning of the transistor, the emitter-base region must be forward-biased and collector-base region must be reverse-biased. In semiconductor circuits, the source voltage is called as the bias voltage. In order to function, bipolar transistors must have both junctions biased. This condition causes a current to flow through the ... bob\u0027s top team dvd

WebIn forward bias, there is an easy path for the flow of current, while in reverse bias, forward current is small. As the depletion layer is thick, there is higher resistance to the flow of … WebJan 4, 2024 · In the above circuit, the applied bias puts the photodiode in reverse bias, so we are operating in photoconductive mode. This circuit could also be used with high reverse and an avalanche photodiode, which would provide high gain for detecting low-level optical signals. To run the circuit in forward bias, simply flip the voltage source around. WebOct 6, 2024 · (i) forward and (ii) reverse bias.
