    NMOS IV characteristic completely different with 2 similar setup

    I am plotting the IV characteristics of the NMOS of 2 similar setups. Here I sweep the Vg from -13 to 13V and vdd from 0 to 50. note that the only difference is that vdd is positive for one but negative for the other. both grounded at the other end. But why I am getting 2 different IV...
