This paper presents a low-power, biologically-inspired silicon neuron based implementation of a chaotic oscillator circuit. The silicon neuron structure is based on Hodgkin-Huxley neuron model. Subthreshold MOSFET and current reuse techniques have been utilized to achieve a low-power consumption of 180.30 nW for the room temperature (27 C) and typical process corner. The chaotic behavior of the circuit is confirmed by calculating the largest Lyapunov exponent. A sensitivity analysis of the proposed chaotic oscillator shows that the circuit maintains the chaotic behavior for five different process corners within the temperature range of 0-60 C. © 2012 Springer Science+Business Media, LLC.
