Interfacing PDM sensors with PFM spiking systems: application for Neuromorphic Auditory Sensors
(Cornell University, 2019)
In this paper we present a sub-system to convert audio information from low-power MEMS microphones with pulse density modulation (PDM) output into rate coded spike streams. These spikes represent the input signal of a ...
