Engineering Negative Differential Resistance in NCFETs for Analog Applications

In negative capacitance field-effecttransistors (NCFETs), drain current may decrease with increasing Vds in the saturation region, leading to negative differential resistance (NDR). While NDR is useful for oscillator design, it is undesirable for most analog circuits. On the other hand, the tendency toward NDR may be used to reduce the normally positive output conductance (g ds) of a shortchannel ...
