Despite the advantages of ternary logic. it has suffered from excessive transistor count and limited noise margin. This work proposes an ultra-efficient nonvolatile ternary flip-flop (FF) based on negative capacitance carbon nanotube field-effect transistors (NC-CNTFETs). By harnessing the negative differential resistance effect in NC-CNTFETs. https://www.chiggate.com/merlot-redbud-tree-sale/
