摘要

本文提出了一种用于短距离通信系统的低功率多通道啁啾-超宽带(C-UWB)发射机。C-UWB发射机产生具有陡峭频谱滚降的宽带调频信号，同时实现占空比操作。为了实现最佳的占空比控制，采用了突发模式传输和陡数字梯度生成技术。采用65nm CMOS实现5- 9ghz C-UWB发射机，用于多通道操作，通道带宽为500MHz。发射机达到1Mb/s的数据速率，从1V电源消耗0.5mW。

A 0.5mW 1Mb/s multi-channel chirp-UWB transmitter with burst-mode transmission and optimized digital gradient

This paper presents a low power multi-channel chirp-UWB (C-UWB) transmitter for short range communication systems. The C-UWB transmitter generates a wideband FM signal with a steep spectral roll-off, while enabling a duty-cycled operation. To achieve an optimum duty-cycle control, burst-mode transmission and steep digital gradient generation techniques are employed. A 5-to-9GHz C-UWB transmitter is implemented in 65nm CMOS for multi-channel operation with a channel bandwidth of 500MHz. The transmitter achieves 1Mb/s data rate, consuming 0.5mW from a 1V supply.
