A Low-Energy High-Density Capacitor-Less I&F Neuron Circuit Using Feedback FET Co-Integrated With CMOS
We have developed a capacitor-less I&F neuron circuit with a dual gate positive feedback fieldeffect transistor (FBFET) and successfully co-integrated FBFET and CMOS in a wafer. By implementing the neuron circuit with FBFET, we can overcome the limits of conventional CMOS, reduce energy c...
