Abstract

A nonlinear interconnection module for a corticonic network is designed and fabricated in a 0.6µm CMOS process. The module uses NMOS transistors in weak-inversion for nonlinearity. A calibration scheme is developed to compensate for the process and temperature variations of the circuit. The designed module has an area of 0.35 sq. mm². It consumes 200mW of power, with 5V power supply. Simulation results show that the circuit is able to implement the target parametric coupling function accurately.
