A Robust-Compact Model to Imitate the Neuronal Dynamics with 2T based FeFET-MOSFET Capturing Temperature Effects

In this work, a robust-compact model based on 2T-ferroelectric FET (FeFET)-MOSFET oscillator based spiking neurons is developed and investigated for external temperature effects. The compact model is rigorously tuned and validated to existing literature for improving the accuracy of investigations. Emulation of neurons that can exhibit both the excitatory and inhibitory dynamics that are typically shown in cortical neurons. The compact model is tuned to reliably mimic regular spiking type cortical neurons with Zr-doped HfO

(HSO) based FeFET(s). The analytical simulations has shown alterations at FeFET oscillations and no visible changes in the digital spikes output for the regular spiking type cortical neurons dynamics.
