Abstract:

This work presents a bandwidth augmented sub-sampling phase-locked loop (BASS-PLL) architecture that features simultaneous out-of-band noise suppression by direct and multipath sampling of the ring oscillator’s (ROs) output and in-band noise suppression via an intrinsic sub-sampling mechanism, ultimately combining the benefits of over-sampling PLLs (OS-PLLs) and sub-sampling PLLs (SS-PLLs) …

A 500-MS/s 94-dB-SFDR Resistive-Input Pipelined-SAR ADC With a Current-Buffer-Based Integrating Sampler and Floating Charge Transferrer

A 500-MS/s 94-dB-SFDR Resistive-Input Pipelined-SAR ADC With a Current-Buffer-Based Integrating Sampler and Floating Charge Transferrer 150 150
Author(s): Xiyu He, Mingyang Gu, Yunsong Tao, Siyu Huang, Zhishuai Zhang, Yi Zhong, Nan Sun, Lu Jie

Abstract:

This work presents a pipelined successive approximation register (SAR) analog-to-digital converter (ADC) with a current-buffer-based integrating sampler that combines an easy-to-drive resistive input with high linearity. To overcome the linearity and swing limitations of conventional current-integrating samplers (CISs), the frontend employs a $G_{m}$ -boosted continuous-time (CT) floating charge transferrer (…

A Self-Powered 21-Component Transient Piezoelectric Energy Harvester With Single-Stage MPPT and Near-Zero Standby Consumption

A Self-Powered 21-Component Transient Piezoelectric Energy Harvester With Single-Stage MPPT and Near-Zero Standby Consumption 150 150
Author(s): Xiudeng Wang, Haohao Shi, Youlan Zeng, Libo Qian, Yang Liu, Guangqian Zhu, Yongyuan Li, Zhangming Zhu

Abstract:

This article presents a rectifierless synchronous inversion and optimal charge extraction (SIOCE) interface with single-stage maximum power point tracking (MPPT) for intermittent vibrations, which are common in real-world applications. Unlike conventional rectifiers that suffer from standby power consumption or rely on inefficient multi-stage conversion, the proposed SIOCE interface circuit decouples …

Abstract:

Emerging applications with highly dynamic digital signal processing (DSP) and machine-learning (ML) workloads demand a hardware platforms that simultaneously deliver high performance, high energy efficiency, and low-latency reconfiguration. Such systems must adapt to evolving algorithms, variable data rates, and multiprogram tenancy without incurring prohibitive switching overhead. The conventional reconfigurable architectures …

A Coherent Polar Phase-Tracking Receiver With High ACR and Relaxed I/Q Generation 150 150
Author(s): Xuansheng Ji, Liqun Feng, Qianxian Liao, Woogeun Rhee, Zhihua Wang

Abstract:

This article presents a coherent polar phase-tracking receiver (PT-RX) for low-power Internet-of-Things(IoT) applications that supports Gaussian frequency-shift keying (GFSK), quadrature amplitude modulation (QAM), and amplitude phase shift keying (APSK). Existing single-path closed-loop receivers achieve low power but suffer from a fundamental tradeoff between loop stability and adjacent channel rejection (…

TD-dAJC: A 100 MS/s 2 pJ/Pixel Time-Domain Weight and Integrating-MAC-Based Direct Analog to MJPEG Compression for Video Sensor Nodes 150 150
Author(s): Harshit Naman, Gourab Barik, Yudhajit Ray, Shreyas Sen

Abstract:

Always-on, high-quality video sensors are increasingly required in wearables, surveillance, and Internet-of-Things (IoT) devices, where stringent energy constraints make efficient in-sensor compression necessary. These systems must support high-definition (HD) and 4 K video, yet conventional digital video compression pipelines consume significant power because high-speed analog-to-digital converters (ADCs) must digitize every pixel, …

Abstract:

This article presents a volumetric integrated voltage regulator (IVR) based on a switched-capacitor-stack-inductor (SCSL) architecture that employs a holistic topology-control-package codesign to overcome the hardware and efficiency bottlenecks of conventional asymmetric multiinductor designs. Based on a discrete-time state-space model, a rigorous root-locus analysis reveals that a rudimentary single voltage-mode control …
