1. An adaptive bypass circuit for a floating level translator, wherein the floating level translator is configured to translate voltage levels from a first voltage domain to a second voltage domain, the adaptive bypass circuit comprising:
a switching circuit coupled across a protection element of the floating level translator; and
a comparator circuit configured to activate the switching circuit to bypass the protection element responsive to a reference rail of the second voltage domain being less than a threshold, and to deactivate the switching circuit to not bypass the protection element responsive to the reference rail of the second voltage domain not being less than the threshold.
