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
Author(s): Baochuang Wang, Xiaonan Wu, Minghao Shang, Lin Cheng

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 …

A Single-Stage CSCR-Based SIDO/DISO Converter With Almost-Lossless Path Switching

A Single-Stage CSCR-Based SIDO/DISO Converter With Almost-Lossless Path Switching 150 150
Author(s): Yuanfei Wang, Yan Lu, Ping Luo, Rui P. Martins, Mo Huang

Abstract:

This article introduces a single-stage single-input– dual-output/dual-input–single-output (SIDO/DISO) converter for autonomous Internet-of-Things (IoT) energy harvesting (EH), utilizing a continuously scalable-conversion-ratio (CSCR) topology. By adopting time-multiplexing control (TMC) instead of ordered-power-distribution control (OPDC), the design achieves independent regulation of input and output voltages and decouples the step-up/step-down …

A 28-nm Digital Transpose SRAM Compute-in-Memory Macro With Accurate/Approximate Dual Mode for Floating-Point Edge Training and Inference

A 28-nm Digital Transpose SRAM Compute-in-Memory Macro With Accurate/Approximate Dual Mode for Floating-Point Edge Training and Inference 150 150
Author(s): Yiyang Yuan, Bingxin Zhang, Yiming Yang, Yishan Luo, Qirui Chen, Haitao Wang, Qihao Liu, Zhiming Chen, Hao Wu, Jinshan Yue, Shidong Lv, Xinghua Wang, Pui-In Mak, Xiaoran Li, Feng Zhang

Abstract:

Static random-access memory (SRAM)-based computing-in-memory (CIM) macros have been widely studied to improve the energy efficiency of edge artificial intelligence (AI) inference tasks. However, less attention has been given to AI training, which requires CIM macros to not only perform matrix multiply-accumulate (MAC) operations but also support matrix transposition. …

A Wide-Dynamic-Range Photovoltaic Energy Harvester With Adaptive Power-Scalable MPPT Control and Direct Power-to-Digital Converter

A Wide-Dynamic-Range Photovoltaic Energy Harvester With Adaptive Power-Scalable MPPT Control and Direct Power-to-Digital Converter 150 150
Author(s): Yuyan Liu, Huajun Zhang, Mustafa Becermis, Jieyu Liao, Mohit Dandekar, Kofi A. A. Makinwa, Qinwen Fan

Abstract:

This article presents a photovoltaic energy harvester (PVEH) that achieves high maximum power point tracking (MPPT) efficiency and power conversion efficiency across a $100~000{\times }$ input power dynamic range (DR) (from $10~{\mu }$ W to 1W). Wide-dynamic-range operation is challenging due to the inherent tradeoff between MPPT accuracy and controller power consumption. …

An 8-bit 4.8-GS/s Four-Channel Time-Interleaved SAR ADC With Ping-Pong Comparators Using Global-Dither-Based Timing-Skew Calibration and Bit-Distribution-Based Offset Calibration

An 8-bit 4.8-GS/s Four-Channel Time-Interleaved SAR ADC With Ping-Pong Comparators Using Global-Dither-Based Timing-Skew Calibration and Bit-Distribution-Based Offset Calibration 150 150
Author(s): Yunsong Tao, Mingyang Gu, Yi Zhong, Lu Jie, Nan Sun

Abstract:

This article presents a global-dither-based timing-skew calibration technique for time-interleaved (TI) analog-to-digital converters (ADCs). By injecting a dithered reference signal globally at the input buffer, the proposed method ensures negligible residual timing skews after calibration. A dither-injection scheme based on source-follower (SF) addition is proposed to suppress the dither kickback …

Abstract:

A high-voltage instrumentation amplifier (HV-IA) is proposed for high-side/in-line current sensing. To achieve low noise and high common-mode (CM) transient tolerance, the IA uses an HV transient-tailored (HV-TT) PMOS input pair with a bidirectional transient shifter (BTS) in the input chopper, achieving 54-V/ $\mu $ s CM transient tolerance (17–37-V …
