摘要

本文提出了一种全集成电容耦合数字隔离器。通过利用自适应载波频率控制（AFC）方案，在保持 250 Mb/s 最高数据速率的同时，显著降低了低数据速率时的功耗。片上隔离电容器可提供 2.5 kVRMS 的隔离额定值，且硅片面积小。发送器（TX）和接收器（RX）采用 180 纳米 CMOS 技术制造。测量结果表明，发送器在 100 kb/s 和 250 Mb/s 时的功耗分别为 0.6 mA 和 1.15 mA。

A 250-Mb/s On-Chip Capacitive Digital Isolator With Adaptive Frequency Control

In this letter, a fully integrated capacitive-coupled digital isolator is proposed. By utilizing the adaptive carrier frequency control (AFC) scheme, the power consumption at low data rate is significantly reduced while maintaining a maximum data rate of 250 Mb/s. The on-chip isolation capacitor provides 2.5-kVRMS isolation rating with compact silicon area. The transmitter (TX) and receiver (RX) are fabricated in a 180-nm CMOS technology. Measurement results show that the transmitter consumes 0.6 and 1.15 mA at 100 kb/s and 250 Mb/s, respectively.
