本文提出了一种用于毫米范围板间通信的单相脉冲调制电感耦合收发器，实现了Gb/s数据速率和3.9pJ/b的能效。通过注入锁定技术将自由运行频率锁定到时钟频率，降低了硬件要求并实现了低能耗。
relaxing hardware requirements and leading to low energy consumption in the transceiver. Figure 11.6.4 shows the spectrum waveform of the receiver output. The 1.09GHz free running frequency is locked to the 1.2GHz clock frequency as the injection-locking occurs. The measured locking range is from 1.02 to 1.36GHz at room temperature. Figure 11.6.4 also shows the recovered clock eye diagram with 2.2ps RMS jitter. 1 2 Recently, short distance board-to-board interconnections are widely employed in portable systems and wearable devices to accommodate many components into an extremely tight footprint. In particular, portable devices such as smart phone and tablet require over 1Gb/s data transfer through ~1mm distance between AP board and a high resolution wide screen display board. Most of display interfaces are implem
