Abstract
Official abstract text for this publication.
According to an exemplary implementation, a level shifter includes a low voltage circuit and a high voltage circuit. The low voltage circuit is configured to provide a differential signal to the high voltage circuit through a capacitive isolation barrier. The high voltage circuit is configured to receive the differential signal from the low voltage circuit through the capacitive isolation barrier so as to level shift the differential signal from a first ground of the low voltage circuit to a second ground of the high voltage circuit. The high voltage circuit is further configured to provide a feedback signal to the low voltage circuit through the capacitive isolation barrier. The low voltage circuit can be configured to receive the feedback signal from the low voltage circuit between edges of the differential signal.
