Author(s): Chenyang Li, Tzu-Han Wang, Dongsuk Kang, Ken Li, Xitie Zhang, Wei-En Lee, Visvesh S. Sathe, Shaolan Li

Abstract:

This article presents a two-step incremental analog-to-digital converter (ADC) that achieves high resolution and energy efficiency while substantially easing the input driving constraints and interstage gain variation. By employing a level-shifted sub-ranging architecture with an input-tracking (IT) feature, the design obviates direct input sampling, thereby significantly relaxing the demands on …

A Low-Power 10Mbps Squaring-First UWB Receiver Using Frequency Hopping and Two-Tone Modulation

A Low-Power 10Mbps Squaring-First UWB Receiver Using Frequency Hopping and Two-Tone Modulation 150 150
Author(s): Lexie Drackley, Aman Gupta, David D. Wentzloff

Abstract:

This paper presents a low-power 10Mbps squaring-first ultra-wideband (UWB) receiver using frequency hopping code-division multiple-access (FH-CDMA) and two-tone OOK modulation for wireless personal area networks (WPAN). The two-tone receiver architecture preserves IF filtering, improves resilience to narrowband interference, and saves power by eliminating the RF local oscillator. FH is applied …

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
Author(s): Feng Bu, Depeng Sun, Dingtao Zeng, Yuan Gao, Bowen Wang, Zhicheng Dong, Xiaoteng Zhao, Hao Xu, Na Yan, Ruixue Ding, Shubin Liu, Zhangming Zhu

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 …

Author(s): Wei-Chun Wang, Shida Zhang, Coleman DeLude, Laith Shamieh, Nael Mizanur Rahman, Isha Chakraborty, Justin Romberg, Saibal Mukhopadhyay

Abstract:

An analog compute-in-memory (CIM) Slepian beamforming (SBF) accelerator is introduced for large-scale multi-input–multi-output (MIMO). The design performs complex-valued vector–matrix multiplication in the analog domain to project 256 I/Q inputs into a low-dimensional Slepian subspace and uses a digital backend with 4-tap FIR filters to generate one output beam. …
