Various embodiments of the present technology may provide methods and apparatus for an auxiliary channel. The auxiliary channel may include a first PMOS transistor connected between two terminals of the auxiliary channel and a second PMOS transistor connected to one of the two terminals, via a resistor, at a first end and to a gate terminal of the first PMOS. The auxiliary channel may further include a support circuit connected to the gate terminals of both the first and second PMOS transistors.
