Analysis of Transient Negative Capacitance Characteristics for Stabilization and Amplification

In this paper, the transient negative capacitance characteristics are thoroughly investigated using a well calibrated TCAD simulations. The stabilization of negative capacitance and amplification is achieved across the series lumped capacitance. The impact of various internal and external factors such as polarization damping, input transition time over the negative capacitance and over amplified voltage across the lumped capacitor has been investigated. We have found that the negative capacitance (NC) effect would not be visible beyond a critical polarization damping and input transition time. Further, we also have explored the stabilization of NC with the parallel lumped capacitance and through MOSCAP.
