  • Patent number: 7570081
    Abstract: An approach is provided in embodiments of the present invention for building multiple-output static CMOS logic gate circuits that share transistors when computing multiple functions from a common set of inputs. In particular, an approach is provided which includes building multiple-output static NAND gates that compute the subfunctions of three or more inputs and building multiple-output static NOR gates that compute the subfunctions of two or more inputs. The approach also includes building multiple-output static XOR-XNOR gates that are capable of computing two-input XOR, three-input XOR, two-input XNOR, and three-input XNOR, and building multiple-output static Propagate-Generate (PG) compound gates. The approach further includes building carry propagate adders, priority encoders, binary-to-thermometers, decoders, etc. that are capable of using the multiple-output static gates embodied in the present invention.
