Hi all,
Please see the following circuit from the book Sedra and Smith. Here the transistor is in saturation even when the gate voltage Vg = grounded. I want to know , when the gate has been grounded there is no positive charges on the gate. Hence no inversion takes place below the gate and no channel is formed. If there is no channel at all then how is that there is a current flow and the transistor is in saturation. Please excuse me if the question is very simple.
thanx in advance
