Integrate-and-Fire (IAF) neurons are widely available in neuromorphic spike-processing applications. Analog LIF neurons are considered a breakthrough to realize fully analog, fully asynchronous spiking neural network implementation for ultra-low-power AI-embedded systems. In this project, you will seek to realize an analog ultra-low-power (thus low energy/spike) LIF neuron, having a very low-frequency spiking rate (e.g., <100Hz). The prerequisite course is Analog integrated circuits. If the design result is promising, the study will be summarized and submitted to IEEE conferences such as ISCAS/BioCAS.
