该论文提出了一种工作在0.55V电压下的非相干IR-UWB数字基带处理器，实现了16Mb/s的数据率和1.6mW的功耗，同时达到±1ns的同步精度。为解决非相干接收机中信号同步困难的问题，该设计采用了低电压低功耗架构和高效同步算法。
sensing applications, in part because they can be easily duty-cycled to achieve extreme energy efficiency. Within pulsed radios, non-coherent (NC) RF front ends that use simple square-and-integrate samplers offer significant energy-per-bit savings over their coherent counterparts [1]. However, such samplers lose phase information and accumulate squared noise over the integration period. While this increases the SNR required to relay a bit reliably, the greater challenge is achieving signal synchronization. Telemetry applications often have small payloads (10 to 100 bits) where synchronization time dominates. Furthermore, synchronization performance is being continually pushed to enable positioning capability. Hence, the ultimate advantage of NC receivers relies on their ability to synchronize efficiently.
