High-speed isolation in ultra-low-power applications

Mark Cantrell, Analog Devices

Isolation has been considered a necessary burden by designers. It is necessary because it makes electronics safe for anyone to use. It is a burden because it limits communication speed and consumes a lot of power and board space. Old-technology optocouplers and even many, newer digital isolators co
