  • Patent number: 8081010
    Abstract: Self Restoring Logic (SRL) provides for SEU tolerance in high speed circuits. An SRL cell is designed to be stable in one of two internal states. Upon an SEU event, the SRL cell will not transition between the internal stable states and recover from an SEU. SRL circuits are realized with SRL storage cells driving succeeding SRL storage cells directly or through combinational logic such that the corruption of any one internal state variable in the driving SRL cell and it's the associated combinational output logic can affect at most one internal state variable of the succeeding SRL cell. An SRL circuit does not allow propagation of single SEU faults.

  • Patent number: 7624368
    Abstract: An application specific integrated circuit is optimized by translating a first representation of its digital design to a second representation. The second representation includes multiple syntactic expressions that admit a representation of a higher-order function of base Boolean values. The syntactic expressions are manipulated to form a third representation of the digital design.

  • Publication number: 20090029353
    Abstract: Described herein are embodiments of a method and device comprising an electronic charge detector capable of detecting the presence of small quantities of electric charge generated through a universal signal generation process that is configured to detect any biological agents and biomolecular targets of interest. Electric charge results from signal molecules binding to affinity molecules that are attached to a detection surface. Electronic circuits are configured to detect the induced electric charges on the detection surface. Additional electronic devices then process useful quantitative data regarding specific biomolecular interaction events.

Each of the n-channel storage transistors has an n-channel load transistor and each of the p-channel storage transistors has a p-channel load transistor. The n-channel load transistors are coupled to be controlled by the p-channel storage circuit and the p-channel load transistors are coupled to be controlled by the n-channel storage circuit. The n-channel load transistors are designed to carry less current than the p-channel storage transistors and the p-channel load transistors are designed to carry less current than the n-channel storage transistors. The storage cell can be used for a Static RAM or for a flip flop.

  • Patent number: 4912348
    Abstract: A method for designing and constructing pass transistor asynchronous sequential circuits, and a class of pass transis tor asynchronous sequential circuits designed in accordance with the inventive method. The inventive circuit design method generates a design for each next state variable, Y.sub.i, of an asynchronous pass transistor circuit, where each design corresponds to a portion of the circuit. In a first preferred embodiment, the invention produces an asynchronous circuit design comprising a pass transistor network and a buffer (having no long term memory) for receiving the output of the pass transistor network. In a second preferred embodiment, the inventive method results in a critical race free, asynchronous circuit design comprising an enable pass transistor network, a disable pass transistor network, and a buffer (including a memory) for receiving the output of both pass transistor networks.

  • Patent number: 4622648
    Abstract: PASS transistors are used to reduce the layout complexity of logic circuits by using PASS transistors connected to pass a first and second input function to an output node in response to selected control signals, thereby to generate a selected output function on the output node. The PASS transistor comprises a transistor capable of passing an input function in response to a control signal applied to the transistor thereby to generate an output function related to the input function. In general, the input function comprises less than all of a set of input variables and the control function comprises one or more of the remainder of the set of input variables.
