Amin, Dinesh Prasad, Naveen Kumar This is a preprint; it has not been peer reviewed by a journal. https://doi.org/ 10.21203/rs.3.rs-4365737/v1 This work is licensed under a CC BY 4.0 License Status: Posted Version 1 posted You are reading this latest preprint version Abstract In this work, we have proposed a Trench gate vertical feedback field-effect transistor (TG-V-FBFET) utilizing the positive feedback mechanism. Simulation and result extraction of the device is done using computer aided TCAD tool (ATLAS-SILVACO). Proposed device exhibits Subthreshold swing (SS) of 0.013mV/dec and on state current (I on ) of 0.1mA/µm with overall I on /I off = 10 10 . Overall on chip area can be reduce up to 66% compared to lateral FBFET counter-part. Further-more, steep subthreshold slope characteristic of the device is exploited for the producing of Leaky Integrate and Fire neuron like spiking behavior. Circuit level simulations consisting proper resetting as well, is also done to properly implement single LIF neuron. Proposed LIF neuron shows a spiking frequency of 0.86GHz/spike and energy of 0.13pJ/spike for input current and threshold potential of 0.9mA and 1.3V respectively.
