A 475-nW Area-Efficient Programmable Analog Feature Extraction Filterbank for Audio Classification 150 150

Abstract:

Audio classification in edge devices has many applications and can be implemented at varying levels of complexity, typically consisting of a feature extractor followed by a classifier. Such devices are often always-on, constantly listening to their surroundings, and have a small form factor; therefore, they require low-power operation and high …
