WebA MOSFET can function in two ways Depletion Mode Enhancement Mode Depletion Mode When there is no voltage across the gate terminal, the channel shows its maximum conductance. Whereas when the voltage across the gate terminal is either positive or negative, then the channel conductivity decreases. WebJun 8, 2013 · A MOSFET's channel is bidirectional so it will conduct equally well in both directions as long as the Vgs turn-on voltage is maintained. From a physics point of view either end of the MOSFET can act as the source, it just depends upon the relative voltages.

WebJul 5, 2012 · MOSFETs will conduct equally in both directions when they are turned "on." An interesting consequence of the body-source connection is that, even if you turn the … WebHowever, to avoid cross conduction with both MOSFETS conducting at the same time across the two polarities of the dual supply, fast switching devices are required to provide some time difference between them turning “OFF” and the other turning “ON”. One way to overcome this problem is to drive both MOSFETS gates separately.
