商品描述
The proliferation of bands and modulation formats calls for a universal software-defined radio (SDR) receiver. This digitizes the received waveforms as soon as possible to relegate most of the functionality to DSP. In order to use low-cost ADCs, we envisage the SDR receiver as a signal conditioner which emphasizes the desired channel and de-emphasizes the rest. This approach requires clock-programmable built-in anti-aliasing pre-filters that attenuate interferers to the extent that ADC can resolve the wanted signal and residual blockers without being overloaded. Most of this work is to design and implement such IF filters. In the rest, a complete portrait of LC quadrature oscillator (QOSC) based on injection locking is offered. It is shown that inserting 90 degrees phase-shifters between the two oscillator cores of the QOSC results in a single-mode oscillation with superior phase-noise and minimum sensitivity to mismatches. Finally, the idea of progressive multiple-node injection is described as a method to widen the lock-range of injection-locked dividers.
商品描述(中文翻譯)
隨著頻段和調變格式的增多,對於通用的軟體定義無線電(SDR)接收器的需求也隨之增加。這種接收器會儘快將接收到的波形數位化,將大部分功能委派給數位信號處理(DSP)。為了使用低成本的模數轉換器(ADC),我們將SDR接收器設想為一個信號調理器,強調所需的通道並降低其他通道的影響。這種方法需要時鐘可編程的內建抗混疊前濾波器,這些濾波器能夠衰減干擾信號,使得ADC能夠解析所需信號和殘留的阻塞信號,而不會過載。大部分的工作是設計和實現這樣的中頻(IF)濾波器。在其餘部分,提供了一個基於注入鎖定的LC正交振盪器(QOSC)的完整描述。研究顯示,在QOSC的兩個振盪器核心之間插入90度相位移器會導致單模振盪,並具有優越的相位噪聲和對不匹配的最小敏感度。最後,描述了漸進式多節點注入的概念,作為擴大注入鎖定分頻器鎖定範圍的一種方法。
