Abstract:

Augmented reality (AR) has been applied to various mobile applications. Modern AR algorithms include neural networks, such as convolutional neural networks (CNNs) and graph convolutional networks (GCNs). The high computational complexity of these networks poses challenges for real-time operation on energy-constrained devices. This article presents the first energy-efficient hybrid CNN-GCN …

A 125–600-MHz IF 75-dB DR Partially Time-Interleaved Bandpass DSM Based on Passive $N$ -Path Filters
A 125–600-MHz IF 75-dB DR Partially Time-Interleaved Bandpass DSM Based on Passive $N$ -Path Filters 150 150
Author(s): Wei Jin, Kong-Pang Pun

Abstract:

This work presents a sixth-order partially time-interleaved bandpass delta-sigma modulator (BP DSM) for direct intermediate-frequency (IF) digitization. There are three resonators, and each of them is built with a passive $N$ -path filter; while two open-loop operational transconductance amplifiers (OTAs) are inserted in between to realize the loop filter. The …

A 16-MHz Crystal Oscillator With 17.5- $\mu$ s Start-Up Time Under 10 $^{4}$ -ppm- $\Delta $ F Injection Using Automatic Phase-Error Correction 150 150
Author(s): Zixuan Wang, Xin Wang, Ka-Meng Lei, Wenjing Zhang, Yunjin Yin, Tailong Xu, Zhikuang Cai, Yufeng Guo, Pui-In Mak

Abstract:

Ast start-up crystal oscillators (XOs) based on energy injection with an auxiliary oscillator (AO) are efficacious in improving the energy consumption of duty-cycled the Internet of Things (IoT) devices. Nonetheless, the frequency mismatch ( $Delta$ F) between the injection frequency and the crystal’s resonance frequency restrains the injection efficiency and …

Author(s): Dong-Hun Lee, Kent Edrian Lozada, Ye-Dam Kim, Ho-Jin Kim, Youngjae Cho, Michael Choi, Seung-Tak Ryu

Abstract:

This article introduces a high-resolution continuous-time delta–sigma modulator (CT DSM) architecture that incorporates a successive approximation register (SAR)-assisted digital noise coupling (DNC) technique and a multi-stage noise-shaping (MASH) structure. The limited maximum stable amplitude (MSA) problem due to the high-order-shaped large quantization error ( $Etextsubscript{1}$ ) in the previous …

Abstract:

Voxel-based point cloud networks composed of multiple kinds of sparse convolutions (SCONVs) play an essential role in emerging applications such as autonomous driving and visual navigation. Many researchers have proposed sparse processors for image applications. However, they cannot properly deal with three problems in the point cloud, including low efficiency …

Full-Duplex Receiver With Wideband, High-Power RF Self-Interference Cancellation Based on Capacitor Stacking in Switched-Capacitor Delay Lines
Full-Duplex Receiver With Wideband, High-Power RF Self-Interference Cancellation Based on Capacitor Stacking in Switched-Capacitor Delay Lines 150 150
Author(s): Sasank Garikapati, Aravind Nagulu, Igor Kadota, Mostafa Essawy, Tingjun Chen, Shibo Wang, Tanvi Pande, Arun S. Natarajan, Gil Zussman, Harish Krishnaswamy

Abstract:

The self-interference (SI) channels in full-duplex (FD) radios have large nano-second-scale delay spreads, which poses a significant challenge in designing SI cancelers that can emulate the SI channel over wide bandwidths. Passive implementations of high delay lines have a prohibitively large form factor and loss when implemented on silicon, whereas …
