ABSTRACT:
An active diode includes a plurality of transistors that implement a built-in offset voltage. The built-in offset voltage size can be determined by sizing of at least one of the plurality of transistors to prevent supply current flow from one supply source into another supply source, thereby preventing current flow from a higher voltage source to a lower voltage source.
