WebAug 16, 2024 · Cut-off mode: In the cut-off mode both the junctions are reverse biased and the BJT does not allow current to flow through it, hence it acts like an open switch. The Forward-active mode of operation is used when the BJT is to be used as an amplifier and the Cut-off and Saturation mode are together used when the BJT is to be used as a switch. Webreduced. This basically eliminates the design trade-off between on state voltage drop, which is inversely proportional to excess control charge, and turn-off time. As a result, MOSFET technology promises to use much simpler and more efficient drive circuits with significant economic benefits compared to bipolar devices.
