A 112-Gb/s PAM4 Receiver With A Phase Equalization AFE in 7-nm FinFET

A 112-Gb/s PAM4 Receiver With A Phase Equalization AFE in 7-nm FinFET 150 150
Author(s): Huanan Guo, Yufeng Yao, Xiang Gao

Abstract:

To reduce the bit-error-rate(BER), equalizers are implemented in high-speed SerDes receivers (RX) to compensate for channel insertion loss and mitigate inter-symbol interference (ISI). Conventional analog front-end (AFE) designs primarily focus on amplitude gain while neglecting the influence of phase shift. This brief presents a phase equalization (PEQ) AFE design …

Frequency-Agile Self-Interference Cancellation in a Wideband Compact Full-Duplex Receiver Using Cascaded Low-Noise and High-Delay-Bandwidth-Product APFs

Frequency-Agile Self-Interference Cancellation in a Wideband Compact Full-Duplex Receiver Using Cascaded Low-Noise and High-Delay-Bandwidth-Product APFs 150 150
Author(s): Xingyu Ma, Wei Li, Shijiao Dong, Ruiyu Lyu, Fan Chen, Yunyou Pu, Chuangguo Wang, Hongtao Xu

Abstract:

Wideband self-interference cancellation (SIC) in a full-duplex (FD) system requires the cancellers to achieve flat nanosecond-scale RF delay while minimizing the noise penalty to the receiver (RX). This work proposes: 1) cascadable hybrid low-noise first-order all-pass filters (APFs) in the first tap of the RF canceller to reduce the noise figure (…

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 Simultaneous Dual-Carrier Transformer-Coupled Passive Mixer-First Receiver Front-End Supporting Blocker Suppression

A Simultaneous Dual-Carrier Transformer-Coupled Passive Mixer-First Receiver Front-End Supporting Blocker Suppression 150 150
Author(s): Jamie C. Ye, Alain H. Antón, Sanaz Sadeghi, Russ H. Huang, Alyosha C. Molnar

Abstract:

A high dynamic range N-path passive mixer-first receiver architecture capable of simultaneously down-converting two arbitrary bands through a single RF port is presented. The architecture consists of two passive mixers arranged in a series configuration with a transformer front-end to minimize cross-loading between mixers while still providing impedance transparency and …
