ABSTRACT:
A method for testing power switches using a logic gate tree, the method includes providing a logic gate tree electrically connected to a plurality of power switches, each output node of the plurality of power switches being electrically connected to a corresponding input node of a logic gate of the logic gate tree; applying a pattern of control signals to the plurality of power switches for controlling on-off states of the plurality of power switches; and determining whether an output voltage signal of an output node of the logic gate tree matches a predetermined value corresponding to the pattern of control signals.
