邻近通信接口电路设计

A Interface Circuit of Proximity Communication

邻近通信技术是一种创新性的芯片连接技术,它采用电容接口进行连接,避免了片外引线,具有高速、高带宽、低功耗等优点,可实现圆片级集成,对未来超大规模芯片集成和高速通信的研制具有重要意义。本文在对邻近通信技术原理进行深入研究的基础上,结合数模混合集成电路设计、电容耦合等基础理论,基于0.18um CMOS工艺设计了满足邻近通信要求的接口电路。仿真结果说明该接口电路能够完成接收信号的放大,且受温度和电源电压的影响较小,稳定性较好。

Proximity Communication is an innovative inter-chip communication technology, which transmits signals chip-to-chip via capacitive coupling instead of through the tangle of pins, wires and circuit boards employed today. Further more, it has the advantage of high-speed, high bandwidth and low power. With Proximity Communication technology, wafer level integrating can be implemented, which is of great importance to high speed communication and VLSI design in the future. Based on an in-depth study of the theory of Proximity Communication, this paper designed an interface circuit which can be used in Proximity Communication with 0.18um CMOS process. Simulation results show that the interface circuit can amplify the receiving signal and is slightly affected by temperature and supply voltage.
