论文摘要
提出了用于低能生物医学微型系统的超宽频段脉冲拉迪奥（UWB-IR）发射机（TX）。高功率效率是通过调节在传输过程中始终在稳态上产生共鸣的LC储罐来实现的。提出了一种新的剪裁sinusoid方案，用于开关键合（OOK）调制，该方案由具有芯片偏置生成的电压夹子电路实现。 TX旨在在3-5 GHz频段内提供高数据率无线链路。该芯片是在130nm CMOS技术中制造的，并具有充分的特征。以230Mbps的数据速率和21pj/b的能源消耗达到了21.3％的最新功率效率。在1m的距离内测量的位率（BER）小于10^-6，而无需平均脉冲。此外，还支持同时进行无线电源和基于VCO的数据传输。还讨论了对无VCO全无线模式的潜在扩展，以进一步降低功耗。
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.
