1. A method for biasing a transistor stack, the method comprising:

  • during a first mode of operation of the transistor stack, coupling gates of transistors of the stack, except an input transistor of the transistor stack, to low impedance nodes;

    during a second mode of operation of the transistor stack, coupling said gates to high impedance nodes; and

    based on the coupling during the first mode and the coupling during the second mode, providing a biasing voltage to each of said gates that is substantially same during both the first and second modes of operation, thereby obtaining a substantially same voltage distribution of a voltage across the transistor stack during said first and second modes of operation.
