Abstract
The low power circuit applications with the negative capacitance field-effect transistors (NCFETs) have been widely examined since NCFETs have a subthreshold swing ( $SS$ ) below 60mV/decade due to the NC effect. However, in the high frequency operation of the NCFET, the NC cannot occur in the ferroelectric layer since it is too fast to switch the polarization, which results in the degradation of the electrical characteristics of that. It is expected that this ferroelectric dynamic behavior can influence on the transient response of the NCFET inverter. Therefore, in this study, the effect of the ferroelectric dynamic behavior on the transient response of the NCFET inverter is investigated by using the technology computer-aided design (TCAD) simulation. As a result, it can be observed that the transient response of the NCFET inverter becomes degraded in the high frequency operation as the viscosity coefficient $(\rho)$ increases, which is related to the ferroelectric dynamic behavior.
