Abstract
The usage of ferroelectric-gate field effect transistors (FeFET) in digital circuits typically involved that of memory applications, but the use of FeFET to implement logic circuits was not completely understood and had not been extensively studied. This paper presented the simulation of electrical properties of a single FeFET and the results of behavioral characterization of FeFET-based basic logic circuits in a commercially available TCAD environment. The all-FeFET CMOS inverter, current mirror, 2-input-NAND and 2-input-NOR logic circuits shown almost the same electrical characteristics as standard MOSFET except for the negligible clockwise hysteresis under the condition of low voltage supply. Moreover, the all-FeFET current mode sensitive amplifier whose component units were all-FeFET common-source amplifier, current mirror and differential amplification, also worked reasonably.
