Analog silicon neurons were proven to be a promising solution for VLSI neuromorphic platform to implement massively scalable computing systems. They possess the advantages of consuming less power and silicon area than digitally designed neurons. This paper compares the differences in power and area consumption between two methods of synapse design for analog neuron models: time-based modulation and current-based modulation. The obtained results demonstrate that under the same technology process (ST CMOS 65nm), the neuron that uses time-based modulation consumes less power (almost six times) and silicon area (about thirty times) but higher energy (twelve times) than that of the current-based modulation
