A 7-Level 18-Wire-State Trio-Signaling Transmitter for MIPI C-PHY 3.0 Interfaces

A 7-Level 18-Wire-State Trio-Signaling Transmitter for MIPI C-PHY 3.0 Interfaces 150 150
Author(s): Junyeong Lee, Myeongjin Oh, Kiwoon Kim, Jung-Hoon Chun

Abstract:

This letter presents a MIPI C-PHY v3.0 TX, which adopts trio-signaling using three wires per lane. Each line supports seven-level signaling, enabling 18 wire states to map 32-bit data into nine symbols, achieving 3.56 bits/symbol efficiency. Balanced coding maintains constant driver current, enhancing SSO noise immunity, and embedded clocking is achieved …

An Optimal Modulation Bits-to-RF Digital Transmitter Using Time-Interleaved Multi-Subharmonic Switching

An Optimal Modulation Bits-to-RF Digital Transmitter Using Time-Interleaved Multi-Subharmonic Switching 150 150
Author(s): Timur Zirtiloglu, Arman Tan, Basak Ozaydin, Ken R. Duffy, Muriel Médard, Rabia Tugce Yazicigil

Abstract:

This article presents a fully integrated bits-to-RF transmitter (Tx) featuring deep power back-off (PBO) enhancements, leveraging a multi-subharmonic switching (multi-SHS) digital power amplifier (DPA) with time-interleaving and a harmonic-rejection digital-to-phase converter (DPC). This work employs a nonuniform optimal modulation (OM) constellation, where symbol probability is inversely related to its amplitude, …

An Antenna-to-Bits F-Band 120-Gbps CMOS RF-64QAM Receiver

An Antenna-to-Bits F-Band 120-Gbps CMOS RF-64QAM Receiver 150 150
Author(s): Youssef O. Hassan, Mohammad Oveisi, Zisong Wang, Payam Heydari

Abstract:

A CMOS 100–140-GHz end-to-end receiver (RX) is presented that integrates the antenna input all the way to the bitstream output, while demodulating 64QAM/16QAM/QPSK entirely in the analog domain. A sequential asynchronous demodulation method enables 120-Gbps operation at a notably small baseband power consumption. Fabricated in a 22-nm FDSOI …

Modern Wireline Transceivers

Modern Wireline Transceivers 150 150
Author(s): Tony Chan Carusone, Timothy O. Dickson, Samuel Palermo, Sudip Shekhar, Mozhgan Mansuri

Abstract:

Over the past two decades, ever-increasing network bandwidth (BW) demands in data centers and high-performance computing systems have fueled exponential growth in per-lane serial link data rates. To keep up with this demand and enable faster communication over BW-limited electrical channels, wireline transceiver architectures and circuit topologies have rapidly evolved …

A 1.54-pJ/b 64-Gb/s 16-QAM Intradyne Coherent Optical Receiver in 28-nm CMOS

A 1.54-pJ/b 64-Gb/s 16-QAM Intradyne Coherent Optical Receiver in 28-nm CMOS 150 150
Author(s): Ahmed E. Abdelrahman, Mohamed Badr Younis, Mohamed Osama Selim, Mohamed Saad Aly, Mahmoud A. Khalil, Pavan Kumar Hanumolu

Abstract:

The rapid growth of data-intensive applications in modern data centers is driving demand for scalable, high-speed, and energy-efficient optical interconnects. Traditional noncoherent modulation schemes, such as pulse amplitude modulation (PAM), are reaching their scalability limits at higher data rates, making coherent detection increasingly attractive due to its higher spectral efficiency. …

A Machine Learning-Inspired PAM-4 Transceiver for Medium-Reach Wireline Links

A Machine Learning-Inspired PAM-4 Transceiver for Medium-Reach Wireline Links 150 150
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 …
