A Low-Power G M-C-Based Continuous-Time ΔΣ ADC With Capacitive Input Feedforward and Duty-Cycled G M Technique

A Low-Power G M-C-Based Continuous-Time ΔΣ ADC With Capacitive Input Feedforward and Duty-Cycled G M Technique 150 150
Author(s): Linran Zhao, Yiming Han, Yaoyao Jia

Abstract:

This article presents a low-power continuous-time (CT) $G_{mathrm {M}}$ -C-based $Delta Sigma $ analog-to-digital converter (ADC) employing capacitive input feedforward and a duty-cycled $G_{mathrm {M}}$ technique to enhance linearity while maintaining high energy efficiency. The ADC employs a CT capacitive network for concurrent signal summation and quantization, enabling input …

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

A 475-nW Area-Efficient Programmable Analog Feature Extraction Filterbank for Audio Classification 150 150
Author(s): Patrice Abbie D. Legaspi, Shubham Yadav, Mark S. Oude Alink, Bram Nauta

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 …
