Abstract: A regulator circuit including output loading sense circuitry where the output loading sense circuitry comprises, in one example, a resistor in the feedback leg of the replica bias regulator, a switch in the feedback leg of the replica bias regulator for bypassing the resistor, and a comparator used to sense the output loading and selectively drive the switch.
Abstract: A circuit for use in conjunction with a portion of a core of an integrated circuit, for shifting a signal from a first voltage level to a second voltage level, wherein the circuit is formed using the same process type transistors (i.e., low voltage transistors) as are used in the core of the integrated circuit.
Abstract: A method, system, and computer program product for designing an integrated circuit. In one example, a standard library is provided having a plurality of standard circuit cells, and a substitute library is provided having a plurality of substitute circuit cells wherein one or more substitute circuit cells correspond to one or more standard circuit cells and the one or more substitute circuit cells have at least one differing electrical characteristic—such as power consumption, quiescent current consumption, speed/response time, leakage current, etc.—than the corresponding one or more standard circuit cells. An initial circuit design is created using the plurality of standard circuit cells of the standard library; and one or more non-critical timing paths are identified in the initial circuit design, the non-critical timing paths including one or more standard circuit cells.
