In this region, it acts like a resistor. What is its resistance? 13. For the MOSFET of Figure 9.36, (a) Find the threshold voltage. (b) If we have a 100-V power supply, for what range of loads can the MOSFET be used as a switch with VGS=6 V? (c) Estimate the ON resistance for VGS=6 V. Ip, DRAIN CURRENT (A)
