Title: Abhronil Sengupta: Innovator in Electronic Neuron Technology

Introduction

Abhronil Sengupta is a prominent inventor based in West Lafayette, Indiana. He has made significant contributions to the field of electronic neuron technology, holding three patents that showcase his innovative approach to neural networks and electronic devices.

Latest Patents

One of his latest patents is the "Spin Orbit Torque Based Electronic Neuron." This electronic neuron device features a thresholding unit that utilizes current-induced spin-orbit torque (SOT). The device implements a two-step switching scheme. In the first step, a charge current through heavy metal (HM) aligns the magnetization of a nano-magnet along the hard-axis, which is an unstable point for the magnet. In the second step, the device receives a current from an electronic synapse, moving the magnetization from the unstable point to one of two stable states. The polarity of the net synaptic current determines the final orientation of the magnetization. Additionally, a resistive crossbar array may function as the synapse, generating a bipolar current that is a weighted sum of the device's inputs.

Another notable patent is the "Event Driven and Time Hopping Neural Network." In this embodiment, a processor stores the membrane potential of a neural unit within a neural network. It calculates changes to the membrane potential occurring over multiple time-steps that have elapsed since the last update. Each of these time-steps is associated with at least one input that affects the membrane potential of the neural unit.
