In a macroscopic approach, a single-chip cortical patch is designed based on a the model of a bifurcating neuron. In this paper, the monolithic design of the bifurcating neuron is presented. The dynamic element is able to generate an arbitrary one-dimensional map with 12-bit resolution. The CMOS design employs a calibration scheme to maintain robustness against process variations. The element is fabrication in a 0.6um CMOS process, and it driven under signals with 1MHz frequency. It covers a die of 0.2 square mm, and consumes 40mW power, with a 5V supply.
