摘要

The characteristics of the ferroelectric-based common-drain, common-source, common-gate, and differential amplifiers are empirically measured and discussed. The effect of varying the input frequency and load resistance on the phase shift of the output signal, the output voltage, and the voltage gain are determined based on experimental results. Then, a physically-derived nonquasi-static model describing the behavior of the aforementioned ferroelectric amplifier configurations is presented. The model is based on the method of partitioned ferroelectric layer and is valid in accumulation, depletion, and the three inversion cases: weak, moderate, and strong. The equations of this model are based on the ferroelectric polarization equations and the standard MOSFET equations that have been modified to account for the inclusion of the ferroelectric layer. The model code is written in MATLABRTM and outputs voltage plots with respect to time. For each amplifier configuration, the accuracy and effectiveness of the model are verified by a few test cases, where the modeled results are compared to empirically-derived oscilloscope plots. Lastly, the application of ferroelectric electronics in space flight systems is discussed.
