Web14 de dez. de 2024 · FET is a device that is usually operated in the constant-current portion of its output characteristics. But if it is operated on the region prior to pinch-off (that is where V DS is small, say below 100 mV), it will behave as a voltage-variable resistor (WE). It is due to the fact that in this region drain-to-source resistance R DS can be controlled by … Web13 de set. de 2024 · 21 1. I suggest that you study how a JFET works. The JFET is a "pinch off device. It needs a V g s < 0 to create the depletion layer that will "pinch the current off". That cannot happen when V g s = 0. Devices that are off when their V g s = 0 do exist: N_channel MOSFETs. – Bimpelrekkie.

Web2 de jan. de 2024 · It's used to bias the gate to 0 volts. Because an N channel JFET works with a range of negative voltages on the gate with respect to the source, biasing this way ensures that the JFET conducts a few mA of current causing the source to rise to a positive value. At this point equilibrium is reached due to negative feedback.
