Abstract

A simple neuron circuit is presented which can generate the sigmoid neuron activiation function (NAF) and its derivative (DNAF) by introducing asymmetric body biasing in the cross-coupled differential pair. The mode of operation is controlled externally. This results in the efficient utilization of the hardware by realizing NAF and DNAF using the same building blocks. The circuit is prototyped and characterized as a proof of concept on 1.5 µm AMI technology.
