标题： A 21.3%-Efficiency Clipped-Sinusoid UWB Impulse Radio Transmitter with Simultaneous Inductive Powering and Data Receiving

摘要： 一种用于低能耗生物医学微系统的超宽带脉冲无线电（UWB-IR）发射器（TX）被提出。 通过调制一个始终在传输期间稳定状态谐振的LC谐振器，实现了高功率效率。 提出了一种新的截断正弦波方案用于开关键控（OOK）调制，该方案通过具有片上偏置生成的电压削波电路实现。 该TX设计用于在3-5 GHz频段内提供高速数据率的无线链路。 该芯片采用130nm CMOS技术制造并进行了全面表征。 在数据速率为230Mbps且能量消耗为21pJ/b时，实现了最先进的功率效率21.3%。 在1米距离下未进行脉冲平均的情况下测得误码率（BER）小于10^-6。 此外，支持同时的无线供电和基于压控振荡器（VCO）的数据传输。 还讨论了向无VCO的全无线模式扩展的潜在可能性，以进一步降低功耗。 显示英文摘要

摘要： An ultra-wide-band impulse-radio (UWB-IR) transmitter (TX) for low-energy biomedical microsystems is presented. High power efficiency is achieved by modulating an LC tank that always resonates in the steady state during transmission. A new clipped-sinusoid scheme is proposed for on-off keying (OOK)-modulation, which is implemented by a voltage clipper circuit with on-chip biasing generation. The TX is designed to provide a high data-rate wireless link within the 3-5 GHz band. The chip was fabricated in 130nm CMOS technology and fully characterized. State-of-the-art power efficiency of 21.3% was achieved at a data-rate of 230Mbps and energy consumption of 21pJ/b. A bit-error-rate (BER) of less than 10^-6 was measured at a distance of 1m without pulse averaging. In addition, simultaneous wireless powering and VCO-based data transmission are supported. A potential extension to a VCO-free all-wireless mode to further reduce the power consumption is also discussed.
