Neuromorphic Audio Sensor
The Tiny Systems and Circuits (TSirc) research group at Aalto University aims to seek a new design methods of integrated circuits (IC) for audio sensor nodes in the era of internet of things (IoT). Inspired by biological cochlea, we leverage excellent power efficiency of Neuromorphic circuits by exploiting Time-Domain analog signal processing.
Time-domain analog circuits exploits temporal representation of analog signals such as pulse-width modulation (PWM) and pulse-frequency modulation (PFM), being free from headroom degradation problem and its associated signal swing loss issue. This attribute makes time-domain circuits highly suitable for low-supply implementation, towards Process-Scalable analog/mixed-signal circuits in advanced CMOS technologies (ex. <10nm).
