A 200 GHz Wideband and Low-Power Direct-Downconversion Receiver Element in 16 nm FinFET Technology

A 200 GHz Wideband and Low-Power Direct-Downconversion Receiver Element in 16 nm FinFET Technology 150 150
Author(s): Ethan Chou, Hesham Beshary, Nima Baniasadi, Ali M. Niknejad

Abstract:

This letter presents a wideband and low-power direct-downconversion 200 GHz receiver element for digital-beamforming applications implemented in 16 nm FinFET technology. Wideband and low integrated receiver noise figure of 9.8 dB across a 21 GHz baseband bandwidth is realized with a differential low-noise amplifier leveraging an active input balun stage, while wideband gain of 29 …

A 0.5-/0.95-dB NF, 50-/25-Ω Configurable CMOS Front-End ASIC for the Readout of Liquid Argon Calorimeter in the LHC

A 0.5-/0.95-dB NF, 50-/25-Ω Configurable CMOS Front-End ASIC for the Readout of Liquid Argon Calorimeter in the LHC 150 150
Author(s): Mietek Dabrowski, Filip Tavernier, Paul Leroux

Abstract:

This article presents the design of a four-channel front-end application specific integrated circuit (ASIC), ATLAS liquid argon front-end (ALFE), developed for the readout of the liquid-argon calorimeter (LAr) detector in the ATLAS experiment at the Large Hadron Collider (LHC). ALFE enables the readout of current signals induced in the LAr …

A 10.9nV/√Hz, 74.9dB-DR, 20MS/s Ultrasound Analog Front End for Fully-Digital Beamforming

A 10.9nV/√Hz, 74.9dB-DR, 20MS/s Ultrasound Analog Front End for Fully-Digital Beamforming 150 150
Author(s): Changde Ding, Yan Zhu, Pengjie Wang, Zhiliang Hong, Jiawei Xu

Abstract:

This letter presents a compact and energy-efficient analog front-end (AFE) circuit for fully-digital beamforming in endoscopic and catheter-based 3D-ultrasound imaging. The AFE converts single-ended analog input from each transducer element into a 10-bit digital output through a low-noise amplifier (LNA) and a 20 MS/s SAR ADC. To minimize chip area …
