ABSTRACT:
In accordance with the teachings of the present invention, a method and apparatus for increasing the efficiency of electrical systems are provided. In a particular embodiment, the apparatus comprises a first electrical component including a self-biasing resistor and at least one input terminal coupled to a power supply, and a second electrical component including at least one input terminal coupled to an output terminal of the first electrical component, and an electrical short circuit connected across the self-biasing resistor in the first electrical component such that current from the power supply bypasses the self-biasing resistor.
