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

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 …

A 14-nm Nonvolatile-Volatile-Fused Compute-In-Memory Macro Based on Logic-Compatible Flash for Plastic Neural Networks

A 14-nm Nonvolatile-Volatile-Fused Compute-In-Memory Macro Based on Logic-Compatible Flash for Plastic Neural Networks 150 150

Abstract:

Designing computing-in-memory (CIM) chips with synaptic plasticity can potentially support energy-efficient on-chip learning in edge devices for rapid local task adaptation. Its silicon implementation is challenging as it requires hybridizing nonvolatile and volatile memory (VM) and customized computational operations. In this work, we propose a plastic CIM (P-CIM) macro featuring: 1) …

A 39.4-mW 300 MHz-BW 70.9 dB-SNDR Hybrid ADC With Resistive Input and 200 fs, rms-Jitter Tolerance

A 39.4-mW 300 MHz-BW 70.9 dB-SNDR Hybrid ADC With Resistive Input and 200 fs, rms-Jitter Tolerance 150 150

Abstract:

This letter presents a power-efficient hybrid ADC architecture: a low-resolution continuous-time (CT) delta-sigma modulator (DSM) followed by a time-interleaved pipeline stage which further quantizes the quantization noise of the DSM. In the frontend CT DSM, the resistive input makes the ADC easy-to-drive, and the direct-charge-dump feedback (DCD FB) provides a …

A Calibration-Free Pipelined-SAR ADC With Cross-Stage Gain-Mismatch Error Shaping and Inherent Noise Shaping

A Calibration-Free Pipelined-SAR ADC With Cross-Stage Gain-Mismatch Error Shaping and Inherent Noise Shaping 150 150

Abstract:

This article presents a calibration-free pipelined-successive-approximation-register (SAR) analog-to-digital converter (ADC) based on the proposed cross-stage gain-mismatch-error shaping (CS-GMES) mechanism. The CS-GMES is realized by including the entire 2nd stage into MES operation to unify the gain error and the 2nd-stage mismatch error. A feedback capacitor provides cross-stage connection and mismatch …
