Abstract :
This paper presents a CMOS neuron circuit design based on the Hindermarsh-Rose (HR) neuron model. In order to be fabricated in a 0.18μm CMOS technology with 1.8V compatible transistors, both time and amplitude scaling of HR neuron model is adopted. This on chip solution also minimizes the power consumption and circuit size, which is ideal for motion control unit of the proposed bio-mimetic micro-robot. Simulation results demonstrate that the proposed CMOS neuron performs the expected waveform with time and amplitude scaled. The chip was fabricated by MagnaChip with an active die area of 1.1mm including I/O pads. The experimental results validate the performance of this CMOS neuron.
