摘要

本文提出了一种可用于RFID和无线传感器应用的能量检测红外-超宽带接收器的数字后端设计。基于一种新的同步估计算法，设计了一种基带处理器。它降低了实现的复杂性和能耗。本文还设计了一种相位分辨率为1.04ns的可编程定时电路。数字后端采用UMC 90nm工艺，功耗222µW，芯片面积140*220µm2。

A digital back-end of energy detection UWB impulse radio receiver

This paper presents a digital back-end design for energy detection IR-UWB receivers which can be adopted in RFID and wireless sensor applications. A baseband processor is designed on the basis of a novel synchronization and estimation algorithm. It reduces implementation complexity and energy consumption. A programmable timing circuitry with 1.04ns phase resolution is also devised in this work. The digital back-end is implemented in UMC 90nm process, with 222µW power and 140*220µm2 die area.
