Question

For the MOSFET circuit given below,

 

a)     The depletion NMOS transistor has IDSS = 4mA and VP = -4V. Given that VDD = +10V and RD = 1kΩ Find the region of operation for the MOSFET and calculate the parameters of VGSID and VDS.

b)     Replace the short circuit that is connected between the gate and the drain with a 1MΩ resistor. In addition, place another 1MΩ resistor between the gate and the reference. Given that K = 0.25mA/V2Vt =2VRD = 500Ω and VDD = +12V. Find the region of operation for the MOSFET and calculate the parameters of VGSID and VDS.
