Analysis and Design of Ultra-Wideband mm-Wave Injection-Locked Frequency Dividers Using Transformer-Based High-Order Resonators
TL;DR: A transformer-based high-order resonator is proposed to improve the locking range (LR) of the millimeter-wave injection-locked frequency dividers (ILFDs) and the operating principles of the proposed high- order resonator are analyzed based on their flattened phase response.
Journal ArticleDOI
An Injection-Current-Boosting Locking-Range Enhancement Technique for Ultra-Wideband mm-Wave Injection-Locked Frequency Triplers
TL;DR: In this paper, an injection-current-boosting (ICB) locking-range enhancement technique is presented to increase the locking range (LR) of the millimeter-wave (mm-wave) injection-locked frequency triplers (ILFTs).

TL;DR: This paper presents a 39 GHz dual-channel transceiver chipset with LTCC package for 5G fixed wireless access (FWA) communication that integrates two variable-gain frequency conversion channels, one LO chain and one SPI block.
Proceedings ArticleDOI
A 22.8-to-43.2GHz tuning-less injection-locked frequency tripler using injection-current boosting with 76.4% locking range for multiband 5G applications
TL;DR: To simplify the system design and meet the multiband requirement, a tuning-less ILFT with an ultra-wide locking range is seen as an appropriate solution for mm-wave multiband 5G applications.
Journal ArticleDOI
An Ultralow Phase Noise Eight-Core Fundamental 62-to-67-GHz VCO in 65-nm CMOS
TL;DR: In this paper, an eight-core fundamental VCO with ultralow phase noise (PN) performance is presented, where two VCO cores are connected together directly to form a VCO cell.
