TexCAC: A Direct-Textile-Attachable Microcontroller Integrating 2-MB MRAM for the Command and Control of Advanced Smart Textiles

TexCAC: A Direct-Textile-Attachable Microcontroller Integrating 2-MB MRAM for the Command and Control of Advanced Smart Textiles 150 150

Abstract:

Advanced smart textiles (ASTs) are textile-integrated electronic systems that enable many applications, including healthcare, robotics, and IoT. ASTs contain a variety of electronic components to enable whole system functionality (batteries, sensors, SoCs, etc.), which all require orchestration from a central command-and-control (CAC) module. The primary functions of the CAC module …

A Two-Step Time-Domain Logic-Compatible Embedded-Flash Computing-in-Memory Macro for On-Device AI

A Two-Step Time-Domain Logic-Compatible Embedded-Flash Computing-in-Memory Macro for On-Device AI 150 150

Abstract:

Computing in memory (CIM) has emerged as a promising architecture that can significantly reduce power consumption and latency in edge artificial intelligence (AI) devices. For battery-constrained edge devices, non-volatile memories (NVMs) are ideal due to their ability to retain neural network parameters even when powered down, ensuring rapid response time …

A 500-MS/s 12-bit Pipeline-SAR ADC Using a PVT-Robust Triple-Cascoded FIA With Virtual Supply Extension

A 500-MS/s 12-bit Pipeline-SAR ADC Using a PVT-Robust Triple-Cascoded FIA With Virtual Supply Extension 150 150

Abstract:

The pipeline-successive approximation register (SAR) analog-to-digital converter (ADC) extends the energy efficiency and the scaling properties of SAR ADCs to the medium-to-high resolutions and high bandwidths typical of classical pipeline ADCs. However, the residue amplifier (RA) is often a performance and energy efficiency bottleneck, especially for high-speed designs in scaled …

A Self-Calibrated NPN-Based Temperature Sensor With ±0.05 °C (3σ) Inaccuracy From −70 °C to 125 °C and 100fJ ${\\cdot}$ K2 Resolution FoM

A Self-Calibrated NPN-Based Temperature Sensor With ±0.05 °C (3σ) Inaccuracy From −70 °C to 125 °C and 100fJ ${\\cdot}$ K2 Resolution FoM 150 150

Abstract:

This article presents a CMOS temperature sensor that achieves both state-of-the-art energy efficiency and accuracy. An NPN-based front-end generates both PTAT and CTAT currents, whose ratio is then digitized by a continuous-time (CT) $\Delta \Sigma $ modulator, which realizes a noise-optimized current-balancing scheme that maximizes the sensor’s resolution. To correct …

A 31.5–36-GHz Low-Spur Digitally Assisted Gain-Boosting Charge-Sharing Locking PLL Achieving 54-fs RMS Jitter

A 31.5–36-GHz Low-Spur Digitally Assisted Gain-Boosting Charge-Sharing Locking PLL Achieving 54-fs RMS Jitter 150 150

Abstract:

This article presents a 31.5–36 GHz digitally assisted gain-boosting (GB) charge-sharing locking (CSL) phase-locked loop (PLL) that achieves record-low reference spurs while maintaining sub-60 fs integrated jitter. In conventional CSL PLLs, reference spur suppression is fundamentally traded against loop bandwidth, whereas ping-pong CSL (PP-CSL) approaches typically require complex duty-cycle calibration. The …

A Stress- and Temperature-Compensated TMR Current Sensor With ±0.13% Sensitivity Variation

A Stress- and Temperature-Compensated TMR Current Sensor With ±0.13% Sensitivity Variation 150 150

Abstract:

This article presents a high-precision tunnel magnetoresistance (TMR)-based non-contact current sensor with enhanced immunity to sensitivity drift. A background sensitivity stabilization loop (SSL) continuously regulates the TMR bias voltage to compensate intrinsic sensitivity variations. Through this closed-loop regulation, sensitivity drift of the TMR sensor induced by temperature, mechanical stress, …

A Line-Connected Q-Sampler-Based Multi-Phase Hybrid Converter

A Line-Connected Q-Sampler-Based Multi-Phase Hybrid Converter 150 150

Abstract:

This article presents a line-connected Q-sampler-based (LQS) multi-phase (MP) hybrid converter for direct conversion from high-rail to point-of-load (PoL). The proposed topology uses an input-parallel switched-capacitor (SC) structure to support “ALL-ON” operation during load transients, while a “multi-source- ${V}_{\mathrm { X}}$ ” control decouples voltage conversion ratio (VCR) from phase count, …

THz-TSI: A Terahertz Wireless Through-Silicon Interconnect Module for Advanced 3-D Integration Applications

THz-TSI: A Terahertz Wireless Through-Silicon Interconnect Module for Advanced 3-D Integration Applications 150 150

Abstract:

By vertically stacking device layers, advanced 3-D integration overcomes traditional planar scaling limits, delivering the bandwidth and power efficiency essential for modern artificial intelligence (AI) and high-performance computing (HPC) integrated systems. However, continued scaling of conventional through-silicon vias (TSVs) and microbumps presents critical bottlenecks due to inherent thermo-mechanical stress, complex …

A Calibration-Free Frequency-Scalable ΔΣ ADC Incorporating PVT-Robust Dynamic Integration

A Calibration-Free Frequency-Scalable ΔΣ ADC Incorporating PVT-Robust Dynamic Integration 150 150

Abstract:

This article summarizes a calibration-free, frequency-scalable $Delta Sigma $ analog-to-digital converter (ADC) which employs dynamic open-loop integrators for low-power sensing systems. The integrators use a capacitive degeneration scheme to obtain an integration factor determined by a capacitor ratio. To enhance process-voltage-temperature (PVT) robustness, bottom-plate level shift (BPLS) and a timer are …
