High-Precision Close-to-Analog Programming of PCM Cells as Devices for AiMC Edge-AI

High-Precision Close-to-Analog Programming of PCM Cells as Devices for AiMC Edge-AI 150 150

Abstract:

This article presents a high-precision close-to-analog programming methodology for phase-change memory (PCM) cells, targeting analog in-memory computing (AiMC) architectures for edge-artificial intelligence (AI) applications. By leveraging an iterative accumulation approach during the verify phase, the proposed technique enhances the effective number of bits (ENOBs) achievable in PCM cells. Experimental validation …

An Ultralow Cross-Regulation Single-Inductor Multiple-Output (SIMO) Buck Converter Using Reordered Power-Distributive Control

An Ultralow Cross-Regulation Single-Inductor Multiple-Output (SIMO) Buck Converter Using Reordered Power-Distributive Control 150 150

Abstract:

A single-inductor multiple-output (SIMO) buck converter employing reordered power-distributive control (RPDC) is presented to achieve ultralow cross regulation. Adedicated power-distribution controller implements RPDC by adaptively adjusting the switching sequence: when the inductor current is insufficient, the switching period is extended, and when excessive, an end phase in the form of …

An 8.62-μW 75-dB DRSoC Fully Integrated SoC for Spoken Language Understanding

An 8.62-μW 75-dB DRSoC Fully Integrated SoC for Spoken Language Understanding 150 150

Abstract:

We present a sub-10- $\mu $ W fully integrated SoC for on-device spoken language understanding (SLU). Its analog feature extractor (FEx) applies global and per-channel automatic gain control (AGC) to extend the system’s dynamic range (DR)—a critical requirement for real-world scenarios, including far-field operations. The on-chip streaming-mode recurrent …
