基于蓝牙低功耗技术的低中频接收器系统设计

The Low IF Receiver System Design Based on Bluetooth Low Energy Technology

介绍了一种遵循蓝牙低功耗技术标准的低中频接收器的完整的系统设计方法,讨论了每个模块的设计,以使总体设计达到最先进的低功耗标准。最后,由选定的系统结构确定ADC的参数要求。本设计可以为低功耗复杂低中频接收器设计提供参考,系统能够达到最小信噪比和更佳动态范围的要求。

Portable wireless electronic devices have become an indispensable part of life. In order to make mobile devices more efficient and long-battery life,the article introduces the whole system design method which follows the standard Bluetooth low energy technology for low-IF receiver. It also discusses the design of each module,so that it could achieve the most advanced low-power standard. Finally,the paper determines the required parameters of ADC by the selected system configuration. A minimum ratio and better dynamic range requirements can be fitted to the system.The design can be a reference for complex low-power low-IF receiver.
