This paper presents a solution for fault-tolerance in logic circuits comprised of Carbon Nanotube FETs (CNTFETs). This work builds on a recently proposed method for errorcorrection called Restorative Feedback (RFB). The RFB method is a variant of Triple-Modular Redundancy (TMR) that utilizes the fault masking capabilities of the Muller C element to provide added protection against transient faults caused by electronic noise. A novel design is proposed for implementing a ternary C element. We also show the ability of RFB method to suppress internal transient noise in CNTFET multi-valued logic (MVL) circuits.
