Abstract

Ultrawideband (UWB) has drawn the interest among the research and wireless communication communities due to its configurability and adaptability, which enables it to coexist with many concurrent services. There are currently various mobile communication standards in use worldwide. The mobile communication industry is under transition phase and experiencing a shift from single system connectivity to multi-system connectivity. The objective is to communicate over varying distances using varying bit rates with a high-speed data and coverage. One of the challenging blocks to design in such transreceiver is the multi-standard low noise ultrawideband (UWB) RF signal source (VCOs) that can provide seamless connectivity among the various standards considered. The VCOs design approach demonstrated in this work can satisfy the present demand of tuning range and noise performance, and reconfigurable for integration in chip form. The measured phase noise is better than -112 dBc/Hz at 100 kHz offset over the tuning range (0.5-2 GHz/2-8 GHz), and to our knowledge this is the best phase noise and highest tuning band of operation using N-push topology with discrete components so far reported

超宽带(UWB)射频信号源

超宽带(UWB)由于其可配置性和自适应性，使其能够与许多并发业务共存，已经引起了研究和无线通信界的兴趣。目前在世界范围内使用的移动通信标准多种多样。移动通信产业正处于转型阶段，正经历着从单系统连接到多系统连接的转变。目标是在不同的距离上使用不同的比特率进行通信，并具有高速数据和覆盖范围。在这种收发器中设计具有挑战性的模块之一是多标准低噪声超宽带(UWB)射频信号源(vco)，该信号源可以在各种标准之间提供无缝连接。本文提出的压控振荡器设计方法可以满足当前对调谐范围和噪声性能的要求，并且可以实现芯片形式的集成。在调谐范围内(0.5-2 GHz/2-8 GHz)，在100 kHz偏置时测量到的相位噪声优于-112 dBc/Hz，据我们所知，这是迄今为止报道的使用离散元件的N-push拓扑的最佳相位噪声和最高调谐频带
