Abstract:

In this article, we present a differentially injection-locked clock multiplier (ILCM) featuring an ultra-wide frequency tuning range (TR) and low jitter, achieved through a compact folded-inductor-based magnetic-flux cancellation technique. A co-designed series-LC dual-mode quadrature ring oscillator (QRO) and edge-combining frequency doubler operating in the mm-wave band jointly extend the TR …

A Compact Reconfigurable Dual-Path Dual-Band LNA for 5G NR FR2 Applications

A Compact Reconfigurable Dual-Path Dual-Band LNA for 5G NR FR2 Applications 150 150
Author(s): Pei Qin, Junyu Wu, Taotao Xu, Yongchun Li, Wenjie Feng, Quan Xue, Wenquan Che

Abstract:

This article presents a reconfigurable dual-path dual-band low noise amplifier (LNA) for fifth generation (5G) millimeter-wave (mmW) communications. A novel band-switching input matching architecture based on the cross-connected transistors is proposed to achieve optimal dual-band input matching and $g_{m}$ -boosting. This architecture allows the dual-band input transistors to share …
