Patent number: 11626403Abstract: A SEU tolerant structure has two logic sections that generate two output signals that are complementary such that a fault which affects one section cannot affect the other section. Adjacent NMOS regions or adjacent PMOS regions contain no logic inversions in the combinational logic or if logic inversions in the combinational logic are present where all gates following the inversion are SEU hard by design. The circuits can be realized using one of a Complex CMOS gate, pass transistor logic, Multiplexor logic, AND-OR logic or OR-AND logic.Type: GrantFiled: May 19, 2021Date of Patent: April 11, 2023Assignee: ICs LLCInventors: Sterling Whitaker, Gary Maki

Publication number: 20140218085Abstract: Fast phase coordinating systems and methods are disclosed. An example system includes a phase locator configured to detect a first phase of a reference signal and a first phase of a coordinating signal after the first phase of the reference signal. An integrator is configured to integrate from the first phase of the reference signal to a location phase of the coordinating signal and integrate oppositely from the first phase of the coordinating signal to a time-shifted phase of the reference signal and output the result. A control function is configured to shift the phase of the coordinating signal in response to output from the integrator.Type: ApplicationFiled: February 4, 2013Publication date: August 7, 2014Applicant: GAIN ICS LLCInventor: Jed Griffin

Patent number: 8081010Abstract: 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.Type: GrantFiled: November 24, 2010Date of Patent: December 20, 2011Assignee: ICS, LLCInventors: Sterling R. Whitaker, Gary K.
