Abstract
This research focuses on a silicon neuron circuit designed utilizing a qualitative neuronal modeling approach. In this circuit, temperature, fabrication mismatch, and secondary effects of transistors cause the difference between the intended characteristics and those in the implemented circuits. Therefore, we have to tune the bias voltages for each neuron instance to realize the desired dynamical behavior after circuit implementation. We constructed an algorithm to automatically find appropriate values for the bias voltages.
