  • Current control circuits
    Patent number: 7911260
    Abstract: Circuit, system and method of current control circuits are disclosed. In one embodiment, a control circuit includes a first MOS transistor and a second MOS transistor. The first source/drains of the first and the second MOS transistors are coupled to an output of a power source. A second source/drain of the first MOS transistor is coupled to a first output node of the current control circuit. A second source/drain of the second MOS transistor is coupled to a second output node of the current control circuit. The control circuit further includes a means to block flow of current from the first output node of the current control circuit to the second output node of the current control circuit.
