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 15-MHz, 2.7-mm2 Notch-Free Hybrid Magnetic Current Sensor With Feedforward Ripple Cancellation and ±0.8% Local Gain Non-Uniformity

A 15-MHz, 2.7-mm2 Notch-Free Hybrid Magnetic Current Sensor With Feedforward Ripple Cancellation and ±0.8% Local Gain Non-Uniformity 150 150

Abstract:

This article proposes a hybrid magnetic current sensor achieving a 15-MHz bandwidth within a compact 2.7-mm2 area. To mitigate the pole–zero mismatch inherent in the two-stage integrator topology, a dual-output Gm-C integrator with subtractor-based compensation is proposed, achieving a ±0.8% local gain non-uniformity. A wideband feedforward ripple suppression scheme cancels …

An Ultra-Low-Jitter Sampling-Filter-Based Charge-Pump PLL With Resistive-Discharge Time-Amplifying Phase-Frequency Detector and Series-Resonance VCO

An Ultra-Low-Jitter Sampling-Filter-Based Charge-Pump PLL With Resistive-Discharge Time-Amplifying Phase-Frequency Detector and Series-Resonance VCO 150 150

Abstract:

This article presents a 13-GHz quadrature charge-pump phase-locked loop (CPPLL) that simultaneously achieves ultra-low jitter and low-spur performance. First, a low-noise resistive-discharge time-amplifying phase-frequency detector (RD-TAPFD) is proposed, achieving extremely low inherent noise and significantly suppressing noise from the following stages. Second, a sampling-based dual-path loop filter effectively suppresses reference …
