An IEEE 802.15.4/4z Coherent Quadrature Hybrid Correlation UWB Receiver in 65-nm CMOS
An IEEE 802.15.4/4z Coherent Quadrature Hybrid Correlation UWB Receiver in 65-nm CMOS 150 150
Author(s): Yunzhao Nie, Woogeun Rhee, Zhihua Wang

Abstract:

This article presents a coherent ultra-wideband (UWB) receiver architecture based on a quadrature hybrid correlation (QHC) method that significantly reduces the digital-correlation-relevant power in the conventional standard-compliant UWB receiver. The proposed QHC receiver front end employs analog correlation, two-step synchronization with a digital-assisted path, and time-interleaved (TI) sampling methods for …

A 4-Element Ka-Band Phased-Array Receiver With Code-Domain Hybrid Beamforming
A 4-Element Ka-Band Phased-Array Receiver With Code-Domain Hybrid Beamforming 150 150
Author(s): Ziyi Lin, Haikun Jia, Chuanming Zhu, Wei Deng, Huabing Liao, Bao Shi, Lujie Hao, Xiangrong Huang, Baoyong Chi

Abstract:

This letter presents a 4-element phased-array receiver with code-domain hybrid beamforming (CDHBF) in 65-nm CMOS technology. Code-division multiplexing is used to fully preserve the flexibility in the digital domain while using a single RF interface, which reduces the RF chain complexity, reduces the chip area, and improves power efficiency. Phase …
