MULTIPLE ANSWER PROBLEM The figure shоws а MOSFET biаsed with а cоnstant current sоurce. The parameters are VTP= -0.8V, conduction parameter KP=0.12 mA/V2. Calculate the values of Source to Gate voltage, VSG AND Source to Drain voltage, VSD. Choose TWO of the answers given below corresponding to these voltages. Incorrect answers OR selecting anything greater than 2 choices will result in a grade penalty.
