A fully integrated CMOS implementation of an integrated-circuit relaxation oscillator neuron, IRON, is proposed. The circuit was designed using a 0.35 /spl mu/m technology. Simulation results show that the circuit is capable of generating bifurcation diagrams of the sine-circle map, while drawing only 4.8 /spl mu/A at 3.3 V power supply, with a 8.23 MHz sine-wave input signal. The total area occupied by the cell was 40 /spl mu/m /spl times/ 40 /spl mu/m.
