In this work, we report a fully CMOS-compatible single silicon neuron device, by exploiting interlinked positive and negative feedback loops. The neuron device exhibits the key features of leaky integrate-and-fire functionality and can produce neuronal oscillations that resemble biological oscillations. The stochastic nature and analog input-sensitivity of the feedback switching dynamics are observed in the device. Moreover, the neuronal oscillations of the two-terminal device do not require any power supplied by external bias lines.
