Abstract:

This article presents a fully integrated output-capacitor-less (OCL) multi-feedback-loop low-dropout regulator (LDO) with an in-built single bipolar junction transistor (BJT)-based voltage and current reference (VCR) for energy-harvesting Internet of Things (IoT) devices. The proposed architecture comprises four loops, which significantly enhance the DC regulation and transient performance of the …

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 …
