  • Latched multivalued full adder
    Patent number: 4390962
    Abstract: A synchronous latched multivalued full adder for processing a first input current having any one of a plurality of multivalues, including a quantizer for receiving current, for generating a sum logical output current and a carry logical output current being a quantization of the received current, and for regenerating the received current from the sum and carry logical output current as an output, an input line for directing the input current to the quantizer as the received current, a feedback line for directing the regenerated current back to the quantizer as the received current, and a clock controlled switching device for coupling the input line to the quantizer while decoupling the feedback line from the quantizer during a setup mode and for decoupling the input line from the quantizer while coupling the feedback line to the quantizer during a hold mode.

  • Synchronous multivalued latch
    Patent number: 4378595
    Abstract: A synchronous multivalued latch for storing logical current values of input current having any one of a plurality of multivalues, including a quantizer for receiving current, for generating a logical current being a quantization of the received current, and for regenerating the received current from the logical current as an output, an input line for directing the input current to the quantizer as the received current, a feedback line for directing the regenerated current back to the quantizer as the received current, and a clock controlled switching device for coupling the input line to the quantizer while decoupling the feedback line from the quantizer during a setup mode and for decoupling the input line from the quantizer while coupling the feedback line to the quantizer during a hold mode.
