摘要

本文介绍了一种用于无线供电RFID应用的3-5 GHz，高输出幅度，基于无载波的超宽带(UWB)发射机。UWB发射机由一个基带脉冲发生器、一个驱动放大器和一个输出片上滤波器组成。基带脉冲发生器和驱动放大器设计为直流零功耗电路，使功率随脉冲速率可扩展。考虑集成电路焊盘和键合线寄生作为输出滤波网络的一部分被吸收，实现封装协同设计。仿真结果表明，该发射机的脉冲能量为2.34 pJ/ s，脉冲幅值为1.63 V。1.8 V电源下的总能耗为18pj /脉冲，相当于13%的能效。

A power scalable and high pulse swing UWB transmitter for wirelessly-powered RFID applications

This paper presents a 3-5 GHz, high output amplitude, carrier-less based Ultra Wideband (UWB) transmitter for wirelessly powered RFID application. The UWB transmitter consists of a baseband pulse generator, a driver amplifier and an output on-chip filter. The baseband pulse generator and the driver amplifier are designed as zero DC power consuming circuit, which enables scalable power with the pulse rate. IC pad and bonding wire parasitics are considered to be absorbed as part of output filtering network, realizing package co-design. The simulation result shows that the proposed transmitter radiates 2.34 pJ/pulse energy with 1.63 V pulse amplitude. The total energy consumption under 1.8 V power supply is 18 pJ/pulse, corresponding to 13% energy efficiency.
