Abstract:

This article presents a 112-Gb/s discrete multitone (DMT) wireline receiver (RX) datapath with a 50-GS/s, 8-bit, 64-way ( $8 \times 8$ ) time-interleaved time-based analog-to-digital converter (TI-TBADC) in a 5-nm FinFET. The TBADC converts the voltage input into a time-domain quantity using a ring oscillator (ROSC). Eight-slice TBADCs, driven from the same …

Author(s): Ramin Javadi, Tejasvi Anand

Abstract:

This article presents an energy-efficient machine learning-inspired PAM-4 wireline transceiver that leverages data encoding at the transmitter (Tx) and feature extraction with classification at the receiver (Rx) to compensate for channel loss ranging from 13 to 26 dB, while maintaining the bit error rate (BER)<10-11. A new consecutive symbol-to-center (CSC) encoding …

IRIS: An Energy-Efficient Spatial Computing SoC for Real-Time Interactive Rendering and Modeling With Surface-Aware 3-D Gaussian Splatting

IRIS: An Energy-Efficient Spatial Computing SoC for Real-Time Interactive Rendering and Modeling With Surface-Aware 3-D Gaussian Splatting 150 150
Author(s): Seokchan Song, Seryeong Kim, Wonhoon Park, Jongjun Park, Sanghyuk An, Gwangtae Park, Minseo Kim, Hoi-Jun Yoo

Abstract:

The 3-D Gaussian splatting (3DGS), based on a machine learning-driven radiance field technique, is rapidly emerging as a next-generation solution in 3-D graphics. Owing to its short modeling time, computational simplicity, and high rendering quality, it is expected to replace traditional 3-D graphics on edge devices. However, its substantial memory …

A 1-8 GHz, 190MHz BB BW Mixer-First Receiver With Bootstrapped Mixer Switches Achieving Over 16dBm In-Band IIP3

A 1-8 GHz, 190MHz BB BW Mixer-First Receiver With Bootstrapped Mixer Switches Achieving Over 16dBm In-Band IIP3 150 150
Author(s): Erwin Hardeveld, Ronan van der Zee, Bram Nauta

Abstract:

In this article, we propose a wideband mixer-first receiver with improved in-band (IB) linearity. It uses bootstrapped N-path mixer switches to achieve a constant on-state gate–source voltage for large IB signals. We analyze the tradeoff between on-state resistance and off-state subthreshold current in conventional mixer switches and introduce a …

A 28-nm 8–28-GHz Eight-Phase Clock Generator Using an Injection-Locked Dual-Feedback Ring Oscillator

A 28-nm 8–28-GHz Eight-Phase Clock Generator Using an Injection-Locked Dual-Feedback Ring Oscillator 150 150
Author(s): Yechen Tian, Junjie Gu, Weitao He, Shuai Liu, Rui Yin, Xiaoliang Shen, Long Kong, Hao Xu, Na Yan

Abstract:

The injection-locked ring oscillator is being widely used in high-speed wireline transceivers to generate multi-phase clocks. The fundamental limit lies in the tradeoff between the number of output phases and the maximum operation frequency for a given technology node. This work proposes the dual-feedback ring oscillator that breaks the tradeoff …
