Muller C-element as majority gate for self-correcting triple modular redundant logic

Technology scaling has increased the susceptibility of integrated circuits (ICs) to experience an incorrect signal (soft error). Triple modular redundancy (TMR) is a type of code that sends a message through a circuit three times in order to determine the most probabilistic value and hence, mitigate soft error. Circuits using TMR logic in aerospace...

Design Automation of Radiation Hardened Mixed Single, Dual, and Triple Mode Redundant Digital Circuits

The fundamental building blocks of all computer electronics, integrated circuits (ICs) are the least expensive way to create the digital circuits needed for processing binary information. A soft error is when a binary switch within a digital circuit flips to its opposite state and causes an electronic device to malfunction. Modular redundancy is a method...

Improved SRAM Circuits for Integrated Circuit Identification Using Mismatch Fingerprint

There is a continuing need for high-level device security to transfer information on penetrable channels, track the device and data, and encrypt valuable data, whether for national security purposes, intellectual property, or company and individual privacy. Obtaining a unique signature for an integrated circuit can be an excellent tool to achieve...
