    Hello all,

    On the pictures, one is the problem and another is a solution in a solution manual. I'm curious why Vsb = Vin = 0.2, since Vin is across the source and ground, but Vsb is across the source and bulk (substrate).

    Thank You

    What is your ground reference? It's the substrate!
