Ferroelectric Field-Effect Transistor Differential Amplifier Circuit Analysis

摘要

This paper investigates the use of FeFETs in a common analog circuit, the differential amplifier. The two input Metal-Oxide-Semiconductor (MOS) transistors in a general MOS differential amplifier circuit are replaced with FeFETs. Resistors are used in place of the other three MOS transistors. Because of the FeFET hysteresis, the FeFET differential amplifier has several different operating modes depending on the FeFETs' prepolarization. Experimental results of the FeFET differential amplifier operation were obtained. Comparisons were made between the FeFET differential amplifier and the standard MOS differential amplifier. The experimental results are discussed.
