A Cryo-CMOS DAC-Based 40-Gb/s PAM4 Wireline Transmitter for Quantum Computing 150 150
Author(s): Niels Fakkel, Mohsen Mortazavi, Ramon W. J. Overwater, Fabio Sebastiano, Masoud Babaie

Abstract:

Addressing the advancement toward large-scale quantum computers, this article presents the first four-level pulse amplitude modulation (PAM4) wireline transmitter (TX) operating at cryogenic temperatures (CTs). With quantum computers scaling up toward thousands of quantum bits (qubits), but having too limited fidelity for robust operation, continuous rounds of quantum error correction (…

Concurrent Body-Coupled Powering and Communication ICs With a Single Electrode

Concurrent Body-Coupled Powering and Communication ICs With a Single Electrode 150 150
Author(s): Jiamin Li, Yilong Dong, Longyang Lin, Joanne Si Ying Tan, Jia Yi Fong, Jerald Yoo

Abstract:

Body-coupled powering (BCP) and body-coupled communication (BCC) utilize the human body channel as the wireless transmission medium, which shows less path loss around the body area. However, integrating both BCP and BCC requires multiple electrodes or alternating the uplink and downlink in the time domain, due to signal interferences and …
