Energy-efficient spiking neural networks based on Tunnel FET

Abstract

Tunnel FETs (TFETs) with steep switching slope have emerged as an attractive device for energy-efficient circuit implementations. In this work, we explore Spiking Neural Network (SNN) based on Tunnel FETs. Neuron and binary image edge detection circuits implemented using 22 nm predictive technology-based bulk MOSFET models and 20 nm Verilog-A-based table model GaSb-InAs heterojunction TFETs are studied. TFET-based implementation is seen to provide better performance at lower power consumption regime, while the MOSFET-based edge detection circuit produces superior performance at higher power regime.
