High speed signal transmission with GMR based magnetocouplers

Summary form only given. With ever increasing data transfer rates between sensitive equipment, the need for high speed, galvanically isolated signal transmission is steadily growing. Standard optocouplers are reaching technological limits at a bandwidth of 25 MHz. Magnetocouplers are theoretically capable of transferring data at rates up to 1 GHz or more. They also feature several other advantages over optocouplers. They can be operated at low supply voltages, have a larger temperature range, and may be integrated with standard VLSI technology.
