摘要

提出了一种用于支持高速、异步、全双工通信的栅极驱动器的完全集成的电隔离器。从微控制器到功率器件的数据传输使用100 Mb/s的移幅键控（ASK）实现，而相反方向的同步通信使用167 Mb/s的移频键控（FSK）实现。基于延迟锁环（DLL）的FSK解调器可以在完全异步通信场景中实现鲁棒操作。原型机采用0.13- $\mu $ m HV CMOS技术制造，面积为2.2 mm2。该系统使用1.5 v低电压供电，总功耗为8.2 mW。在各自的最大数据速率下，测量到的传播延迟对于ASK小于8 ns，对于FSK小于4 ns。

A Fully Integrated Galvanic Isolator for Gate Drivers With Asynchronous 100/167 Mb/s ASK/FSK Full-Duplex Communication

A fully integrated galvanic isolator for gate drivers that supports high-speed, asynchronous, full-duplex communication is presented. Data transmission from the microcontroller to the power device is achieved using amplitude-shift keying (ASK) at 100 Mb/s, while simultaneous communication in the opposite direction is implemented using frequency-shift keying (FSK) at 167 Mb/s. A delay-locked loop (DLL)-based FSK demodulator enables robust operation in a completely asynchronous communication scenario. Prototypes were fabricated in a 0.13-

$\mu $

m HV CMOS technology, covering an area of 2.2 mm2. The system operates from a low 1.5-V supply with a total power consumption of 8.2 mW. Measured propagation delays are under 8 ns for ASK and below 4 ns for FSK at their respective maximum data rates.
