提出了一种异步脉冲发射机，以实现电感耦合链路的低功耗。传统的异步发送器，H桥电感耦合发送器，消耗大的静态（DC）电流消耗。因此，发射功率耗散在总电感耦合功率耗散中占主导地位。所提出的脉冲电感耦合发射器消除了静态（DC）电流消耗。它提供了线性功率可伸缩性，这显著降低了功耗，特别是在低功耗移动的应用的低数据速率操作时。为了验证所提出的技术，我们设计并制造了TSMC 0.18 µm互补金属氧化物半导体（CMOS）技术的测试芯片。在测试芯片中实现了脉冲发射机和传统H桥发射机，以进行比较。与传统的发射机相比，在1.5 Gbps和100 Mbps的1/60的功率降低到1/4。还提出了一种抗串扰感应耦合接收机，用于使用所提出的脉冲发射机的低功率中继传输。串扰保护电路实现在接收器中，以忽略串扰。使用建议的收发器以高达400 Mbps的速率成功传输数据。
An asynchronous pulse transmitter is proposed to achieve low power in inductive-coupling link. The conventional asynchronous transmitter, H-bridge inductive-coupling transmitter, consumes large static (DC) current consumption. Therefore the transmit power dissipation is dominant in the total inductive-coupling power dissipation. The proposed pulse inductive-coupling transmitter eliminates the static (DC) current consumption. It provides linear power scalability which significantly reduces the power consumption especially at low data rate operation for low-power mobile applications. To verify the proposed technique, we designed and fabricated test chips in TSMC 0.18 µm complementary metal oxide semiconductor (CMOS) technology. Both proposed pulsed transmitter and conventional H-bridge transmitter is implemented in the test chip for comparison. Power reduction to 1/4 at 1.5 Gbps and 1/60 at 100 Mbps is achieved compared to the conventional transmitter. Also a crosstalk immune inductive-coupling receiver is presented for low-power relayed transmission using the proposed pulse transmitter. Crosstalk guard circuit is implemented in the receiver to ignore crosstalk. Data is successfully transferred using relayed transmission with proposed transceiver at up to 400 Mbps.
