i. Sketch Forward Biased Safe Operating Area (FBSOA) of Power
MOSFET device and describe its boundary limits. (Marks: 5)
ii. Using the Gate Charge curve depicted in Figure 1, calculate
the maximum device Turn ON time if a load of 5A is attached with
MOSFET. The device needs to be operated at VGS= 8V with an
available constant gate input current IG=x mA. (x= last two digits
of your roll number)
