Correction to “Leveraging Negative Capacitance CNTFETs for Image Processing: An Ultra-Efficient Ternary Image Edge Detection Hardware”

In the above article [1], Fig. 5(b) belonged to another circuit (the Fe-CNTFET-based 2-transistor Schmitt trigger binary inverter, which is similar in the schematic to the circuit shown in Fig. 5 (a) of the above artice [1] but with different flat band voltages), which was inserted in the revised version of the article [1] by an unintentional mistake. The load line analysis of the circuit shown in Fig. 5 (a) of the article [1] is shown in Fig. 1. For more clarity, the load line analysis has been plotted with more detail for V_in = 0.3V to 0.5V to indicate the performance of the ternary inverter in logic “1,” which matches the related VTC curve (Fig. 5 (c) shown in reference [1]).
